NEUTRON STARS

Newly created strontium, an element used in fireworks, has been detected in space for the first time following observations with ESO’s Very Large Telescope. The detection confirms that the heavier elements in the Universe can form in neutron star mergers, providing a missing piece of the puzzle of chemical element formation. The video is available in 4K UHD. The ESOcast Light is a series of short videos bringing you the wonders of the Universe in bite-sized pieces.

Astronomers have used accurate timing of pulsar signals to determine the mass of a tiny neutron star and its white dwarf companion, showing that the neutron star is the most massive ever identified. However this is more than an exercise in finding new record holders, neutron stars are held up from collapsing into a black hole by quantum mechanics and nuclear physics, and these extreme conditions are at the limits of our theoretical understanding. So finding the upper mass limit of neutron stars gives important information on the conditions inside nuclear matter.

Scientists have observed a collision of two of the universe's most extreme objects. And a mission to Jupiter's moon Europa makes an important step forward. SciShow has a spinoff podcast!

But perhaps nothing stranger than the stuff at the core of neutron stars. Gravity and pressure are responsible for everything we see around us. Because it's the pressure that fused together atoms in the core of stars that eventually produced the carbon, oxygen, and other elements that keep us and everything alive. Much bigger stars went supernova, collapsing down under gravity and creating even heavier elements. Even bigger stars collapse down so far, they create a singularity, ripping a black hole into the fabric of the universe. But there's a slightly smaller size of star that doesn't manage to go black hole, but does crush down the atoms of its core into neutrons, creating a neutron star, the densest objects in the universe. But it doesn't stop there, because at the core of neutron stars, the up and down quarks that make up neutrons can fuse with each other to create a much heavier type of quark, a strange quark. The strange matter that is made up of strange quarks has the ability to turn any other type of matter into strange matter. This means that if quark stars collide and explode, they could scatter bits of strange matter, or strangelets, across space. And if any of those strangelets were to collide with Earth, it could spell the end of our entire planet.

Underneath the crust of spinning neutron stars, there’s a material that is not only strong, but looks like pasta? Nuclear pasta to be exact. Here’s what else scientists know. The James Webb Space Telescope Is Delayed (Again)! What Is Happening? - https://youtu.be/KiHR1wdRdug Read More: The Elasticity of Nuclear Pasta https://arxiv.org/pdf/1807.02557.pdf “The breaking strain of materials in neutron star (NS) crusts are relevant for a variety of electromagnetic and gravitational wave phenomena. Crust breaking may occur in magnetar outbursts, resonant crust shattering in NS mergers, and in the starquake model for pulsar glitches. Likewise, the shear modulus of crust matter may affect the oscillation frequency of magnetar flares, the damping of r-modes, and determine the height and lifetime of mountains on a NS.” Nuclear Pasta In Neutron Stars May Be The Strongest Material In The Universe https://www.sciencenews.org/article/nuclear-pasta-neutron-stars-may-be-strongest-material-universe?tgt=nr “About a kilometer below the surface of a neutron star, atomic nuclei are squeezed together so close that they merge into clumps of nuclear matter, a dense mixture of neutrons and protons. These as-yet theoretical clumps are thought to be shaped like blobs, tubes or sheets, and are named after their noodle look-alikes, including gnocchi, spaghetti and lasagna.” LIGO: Sources and Types of Gravitational Waves https://www.ligo.caltech.edu/page/gw-sources “Continuous gravitational waves are produced by a single spinning massive object, like an extremely dense star called a neutron star.

An object called GRB 150101B has been studied using the Chandra X-Ray telescope. It was probably generated by a neutron-star merger. -- Full Story: https://www.space.com/42158-another-neutron-star-crash-detected.html Credit: NASA/CXC/A. Hobart

On October 16, 2017, astronomers excitedly reported the first detection of electromagnetic waves, or light, from a gravitational wave source. Now, a year later, researchers are announcing the existence of a cosmic relative to that historic event. The discovery was made using data from a host of telescopes including NASA’s Chandra X-ray Observatory. The object of the new study, called GRB 150101B, was first reported as a gamma-ray burst detected by Fermi in January 2015. This detection and follow-up observations show that this new object shares remarkable similarities to the neutron star merger and gravitational wave source discovered by the Advanced Laser Interferometer Gravitational Wave Observatory, and its European counterpart Virgo in 2017 known as GW170817. The latest study concludes that these two separate objects may, in fact, be related. The researchers think both GRB 150101B and GW170817 were most likely produced by the same type of event: the merger of two neutron stars. This is a catastrophic collision that generated a narrow jet, or beam, of high-energy particles. The jet produced a short, intense burst of gamma rays, a high-energy flash that can last only seconds. This was followed by an afterglow in optical light that lasted a few days and X-ray emission that lasted much longer. Scientists think both of these events involved kilonovas, that is, powerful explosions that release large amounts of energy and can produce elements like gold, platinum and uranium. Understanding these explosions helps astronomers trace our cosmic ancestry. There is still a lot to learn about these events, but Chandra is poised to help in this new era of combined gravitational wave and electromagnetic investigations into our Universe.

Scientists understand gravity pretty well when it comes to two objects, but add a third, and you’ve got chaos—a system that’s impossible to explain with our simplest equations. But you also have a way to test the limits of Einstein’s theory of gravity. You’re probably aware of the fact that there are a lot of outstanding questions about our universe—like what is dark energy, what is dark matter, and why can’t one unified physics theory explain both the biggest and smallest objects in the universe? https://gizmodo.com/einsteins-theory-of-gravity-holds-up-on-test-of-a-three-1827319579 http://www.wochit.com This video was produced by YT Wochit Tech using http://wochit.com

The spectacular merger of two neutron stars that generated gravitational waves announced last fall likely did something else: birthed a black hole. This newly spawned black hole would be the lowest mass black hole ever found. A new study analyzed data from NASA's Chandra X-ray Observatory taken in the days, weeks, and months after the detection of gravitational waves by the Laser Interferometer Gravitational Wave Observatory, or LIGO, and gamma rays by NASA's Fermi mission on August 17, 2017. While nearly every telescope at professional astronomers' disposal observed this source, known officially as GW170817, X-rays from Chandra are critical for understanding what happened after the two neutron stars collided. From the LIGO data astronomers have a good estimate that the mass of the object resulting from the neutron star merger is about 2.7 times the mass of the Sun. This puts it on a tightrope of identity, implying it is either the most massive neutron star ever found or the lowest mass black hole ever found. The previous record holders for the latter are no less than about four or five times the Sun's mass. The Chandra observations are telling, not only for what they revealed, but also for what they did not. If the neutron stars merged and formed a heavier neutron star, then astronomers would expect it to spin rapidly and generate a very strong magnetic field. This, in turn, would have created an expanding bubble of high-energy particles that would result in bright X-ray emission. Instead, the Chandra data show levels of X-rays that are a factor of a few to several hundred times lower than expected for a rapidly spinning, merged neutron star and the associated bubble of high-energy particles, implying a black hole likely formed instead.

Neutron stars are the ultra dense cores of massive stars that collapse and undergo a supernova explosion. This neutron star is located within the remains of a supernova — known as 1E 0102.2-7219 (E0102 for short) — in the Small Magellanic Cloud, located 200,000 light years from Earth. E0102's neutron star is different from most others because it has both a low magnetic field and does not have a star in orbit around it. Its remnant is also unusual because it contains high levels of oxygen like two other well-known supernova remnants, Cassiopeia A and Puppis A. These oxygen-rich supernova remnants are important for understanding how massive stars fuse lighter elements into heavier ones before they explode. Future observations of E0102 at X-ray, optical, and radio wavelengths should help astronomers understand the origin of this lonely neutron star.

A distant and lonely neutron star has been discovered outside the Milky Way galaxy for the first time. Neutron stars are the ultra-dense cores of massive stars that collapse and undergo a supernova explosion. 1E 0102.2-7219 is a supernova remnant, the stellar debris field left behind after the giant star exploded. Data from NASA's Chandra X-ray Observatory and other telescopes points to a celestial bull's eye where the neutron star was found. Unlike many other neutron stars, this one has a very low magnetic field and no stellar companion. Astronomers will continue to observe this object at X-ray, radio, and visible light wavelengths to learn more about this cosmic oddity.

The NASA/ESA Hubble Space Telescope (reddish background image/supernova remnant 1E 0102.2-7219 in green), the MUSE instrument on ESO’s Very Large Telescope (red ring with a dark center) and the NASA Chandra X-Ray Observatory (blue and purple images) were used to create this a new composite image. “The blue spot at the centre of the red ring is an isolated neutron star with a weak magnetic field,” according to the European Southern Observatory (ESO). -- Full Story: https://www.space.com/40241-neutron-star-colorful-galaxy-clouds-discovery.html Credit: ESO

Jan. 24, 2018 Dr. Eliot Quataert (University of California, Berkeley) Recently one third of the world's astronomers became involved in observing a distant and violent event, when two neutron stars collided and exploded. This represented the first time in history that a cosmic event was observed with both gravity waves and light -- the birth of "multi-messenger astronomy." Dr. Quataert gives a non-technical history of how we are now able to find gravity waves, what happens during such a merger, and why we now believe that much of the gold, platinum, uranium and other heavy elements in the universe is assembled in such mergers.

The findings solve a forty year old mystery that’s baffled scientists ever since neutron stars were first discovered. *New clues about the recipe for making stars Astronomers have shed fresh light on the importance of hydrogen atoms in the birth of new stars. Only hydrogen molecules are thought to directly fuel star formation. But new research shows there are more hydrogen atoms than molecules even in young galaxies that are making a lot of new stars. *Midwest Meteor The citizenry of the American mid-west have been treated to an unexpected celestial spectacular with the evening skies lit up by a bright meteor and sonic boom. People in the states of Ohio and Michigan and across the border in Ontario Canada witnessed the event around 8’0 clock local time. *No link between earthquakes and the full Moon A new study has provided more evidence to dispel an enduring myth that large earthquakes tend to happen during certain phases of the Moon or at certain times during the year. The findings confirm that this bit of earthquake lore is incorrect. *Titan has a sea level just like Earth A new study has confirmed that just like Earth – Saturn’s moon Titan has a sea level. The discovery adds to a growing list of similarities between Earth has this hostile alien world. *The Science Report 2017 confirmed as one of the three warmest years on record.

A few weeks ago we discussed the possibility of LIGO having detected two neutron stars colliding, which would have developed what's known as an optical counterpart. It was determined that we were detecting the final seconds of two neutron stars orbiting around each other just before they collided. === CONTINUE THE CONVERSATION === Twitter.com/TMRO Facebook.com/TMROTV YouTube.com/TMRO Reddit.com/r/tmro Twitch.tv/TMRO TMRO.tv === OUR REAL-TIME DISCORD CHANNEL === All of the TMRO Shows are created and maintained in our Discord channel.

Though we know neutron stars are small and extremely dense, there are still many aspects of these remnants of explosive deaths of other stars that we have yet tounderstand. NICER, a facility to be mounted on the outside of the International Space Station, seeks to find the answers to some of the questions still being asked about neutron stars. By capturing the arrival time and energy of the x-ray photons produced by pulsars emitted by neutron stars, NICER seeks answer decades-old questions about extreme forms of matter and energy. Data from NICER will also be used in Sextant, an on-board demonstration of pulsar-based navigation.

NASA has selected a science mission that will allow astronomers to explore, for the first time, the hidden details of some of the most extreme and exotic astronomical objects, such as stellar and supermassive black holes, neutron stars and pulsars. Objects such as black holes can heat surrounding gases to more than a million degrees. The high-energy X-ray radiation from this gas can be polarized – vibrating in a particular direction. The Imaging X-ray Polarimetry Explorer (IXPE) mission will fly three space telescopes with cameras capable of measuring the polarization of these cosmic X-rays, allowing scientists to answer fundamental questions about these turbulent and extreme environments where gravitational, electric and magnetic fields are at their limits.

A neutron star is the collapsed core of a large star. Neutron stars are the smallest and densest stars known to exist. With a radius on the order of 10 km, they can, however, have a mass of about twice that of the Sun.

Like Pokemon Go, we’ve collected them all. Okay fine, I’m still looking for a Tauros, and so I’ll continue to wander the streets, like a zombie staring at his phone. Now, according to my attorney, I’ve fulfilled the requirements for shamelessly jumping on a viral bandwagon by mentioning Pokemon Go and loosely connecting it to whatever completely unrelated topic I was working on. Any further Pokemon Go references would just be shameless attempts to coopt traffic to my channel, and I’m better than that. It was pretty convenient, though, and it was easy enough to edit out the references to Quark on Deep Space 9 and replace them with Pokemon Go. Of course, there is a new Star Trek movie out, so maybe I miscalculated. Anyway, now that we got that out of the way. Back to rare and exotic stellar objects. There are the white dwarfs, the remnants of stars like our Sun which have passed through the main sequence phase, and now they’re cooling down. There are the neutron stars and pulsars formed in a moment when stars much more massive than our Sun die in a supernova explosion. Their gravity and density is so great that all the protons and electrons from all the atoms are mashed together. A single teaspoon of neutron star weighs 10 million tons. And there are the black holes. These form from even more massive supernova explosions, and the gravity and density is so strong they overcome the forces holding atoms themselves together. White dwarfs, neutron stars and black holes. These were all theorized by physicists, and have all been discovered by observational astronomers. We know they’re out there. Is that it? Is that all the exotic forms that stars can take? That we know of, yes, however, there are a few even more exotic objects which are still just theoretical. These are the quark stars. But what are they? Let’s go back to the concept of a neutron star. According to the theories, neutron stars have such intense gravity they crush protons and electrons together into neutrons. The whole star is made of neutrons, inside and out. If you add more mass to the neutron star, you cross this line where it’s too much mass to hold even the neutrons together, and the whole thing collapses into a black hole. A star like our Sun has layers. The outer convective zone, then the radiative zone, and then the core down in the center, where all the fusion takes place. Could a neutron star have layers? What’s at the core of the neutron star, compared to the surface? The idea is that a quark star is an intermediate stage in between neutron stars and black holes. It has too much mass at its core for the neutrons to hold their atomness. But not enough to fully collapse into a black hole. In these objects, the underlying quarks that form the neutrons are further compressed. “Up” and “down” quarks are squeezed together into “strange” quarks. Since it’s made up of “strange” quarks, physicists call this “strange matter”. Neutron stars are plenty strange, so don’t give it any additional emotional weight just because it’s called strange matter. If they happened to merge into “charm” quarks, then it would be called “charm matter”, and I’d be making Alyssa Milano references. And like I said, these are still theoretical, but there is some evidence that they might be out there. Astronomers have discovered a class of supernova that give off about 100 times the energy of a regular supernova explosion. Although they could just be mega supernovae, there’s another intriguing possibility. They might be heavy, unstable neutron stars that exploded a second time, perhaps feeding from a binary companion star. As they hit some limit, they converting from a regular neutron star to one made of strange quarks. But if quark stars are real, they’re very small. While a regular neutron star is 25 km across, a quark star would only be 16 km across, and this is right at the edge of becoming a black hole. If quark stars do exist, they probably don’t last long. It’s an intermediate step between a neutron star, and the final black hole configuration. A last gasp of a star as its event horizon forms.

Delving into the depths of the universe, Dr. Arnau Rios Huguet shows us that we should not be afraid of the unknown, but embrace it and marvel in the pleasure of the unknown. By walking us through recent developments in physics, Arnau shows us the wonders of the universe and highlights that it is anything but ordinary Dr. Arnau Rios Huguet is a STFC Advanced Fellow at the Nuclear Theory Group of the University of Surrey. One of his major research goals is to obtain a time-dependent Green's functions approach for nuclear reactions, including the effect of beyond mean-field correlations. In his research, he has studied nuclear systems, such as nuclear or neutron matter, which have common properties with atomic nuclei. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

Pulsars are an exotic astronomical object left over from exploding stars. Mysterious as they may be, science has helped us to reveal several facts about these cosmological rogues.

Our video walks you through the formation of neutron stars and their various subtypes and consequences. Neutron stars form when massive stars-- stars with a mass between 8 times that of our sun and 20 times that of our sun-- collapses. The gravitation force increases so much that protons and electrons form neutrons, leaving a super dense, super hot care: a neutron star. Pulsars, also known as pulsating radio stars, are neutron stars that rotate, are highly magnetized, and emit beams of electromagnetic radiation. Pulsars move at incredibly fast speeds and can only result from high mass stars. When neutron stars die, they create black holes. Material around the supermassive black hole forms an incredibly accretion disk that emits an enormous amount of radiation. This creates a magnetic environment that produces twin jets of material that courses into space for millions of lightyears: also known as quasars. Finally, magnetars are special pulsars that have a stronger magnetic field, rotate more slowly, and release much higher energy gamma radiation bursts than normal pulsars. The incredibly strong magnetic field can create massive destruction to objects near the magnetar and more far reaching consequences as well. You should probably be more worried about your finals than the effects of a magnetar, but if one came close, it might be a good idea to tell your orthodontist.

Professor Dong Lai Department of Astronomy Cornell University Extreme Physics and Astrophysics of Neutrons Stars Neutron stars are associated with some of the most exotic phenomena and environments in the universe. They have been observed in all electromagnetic wave bands, from radio to gamma rays, and are likely to be detected in gravitational waves in the next few years. Their strong gravities, high densities and magnetic fields provide a unique avenue for exploring physics under extreme conditions. In this talk, I will highlight recent progress and discuss future prospects in the astrophysics of neutron stars.
