People often ask: "how big is the biggest star?" But I reckon the more interesting question is how small are the smallest stars? Because when you get down to the smallest stars, there's a huge grey area between what is a star and what is a planet. Sub-brown dwarfs, planemos, rogue planets - how do we actually tell them apart?

April 25, 2019 Phillips Auditorium Sofia Ramstedt Uppsala U. Host: Rodolfo Montez Abstract: The deaths of stars are always preceded by more or less massive stellar winds. In the case of low- to intermediate mass stars, these winds are the means by which material from the stars is recycled in galaxies. Accurate measurements of the wind physical properties provide constraints for hydrodynamical models which study wind formation and evolution. Estimates of wind density and temperature also form the base for any further research into abundances of different elements, isotopes and molecules in the recycled material. Furthermore, to determine wind gas-to-dust mass ratios holds the key to investigations of extragalactic objects and the impact of these common stars across the Universe. We have lately performed detailed studies of the circumstellar envelopes (CSEs) around nearby (500 pc) stars on the Asymptotic Giant Branch (AGB) with ALMA. The properties of the wind which has created the CSE, can be derived by mapping the CO line emission. We started with a smaller sample of binary stars to investigate the formation and importance of circumstellar asymmetries and structure. To interpret the complex observations, several new analysis tools had to be assembled and tested. These tools are now put to use for the DEATHSTAR project in which we are mapping all nearby AGB stars starting in the southern sky. The goals are to provide the most accurate AGB wind properties to date, and to consistently determine the gas-to-dust mass ratios. I will present results and current status.

The smallest stars in the universe are Red Dwarfs. In fact, the smallest stars in the universe have just 7.5% the mass of the Sun. But Red Dwarfs are the longest-lived stars with lifespans stretching from 1 trillion to 12 trillion years. That means the oldest red dwarf star in the universe is just getting started, and the first red dwarf to ever form in the universe will still be around for trillions of years to come. But today's red dwarfs are violent stars, though they will slowly age and cool to become white dwarfs and then ultimately black dwarfs. When the last red dwarf dies, there will be no more stars shining in the universe. 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/bBaTtKWcsrA 🔴 Watch my most recent upload: https://goo.gl/QbRcE2 🚀 Help me improve the channel by joining the community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you. 🐟 From out of town?

Daniela Calzetti U.Mass, Amherst Understanding galaxy evolution requires understanding star formation and its dependence on the local environment, spanning the scales from individual stars to kiloparsec–size structures. The physical conditions within galaxies determine the formation of stars, star clusters, and larger structures, and their subsequent evolution. HST observations of external galaxies have enabled the characterization of the young stellar populations with unprecedented accuracy and detail, thus aiding the census and description of those populations. These observations are being used to quantify the spatial distribution and clustering of young stars, and investigate the impact and imprint of the physical conditions of both the local and global environment on the formation and evolution of the multi-scale structures. I will concentrate mainly on the results of the Legacy ExtraGalactic UV Survey (LEGUS), an HST Treasury programs that is investigating these issues using multi-color imaging, from the near-UV to the I, of a sample of nearby galaxies. I will also briefly introduce successor programs that promise to expand our understanding of star formation on galactic scales.

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Our current theory of evolution holds that all life on Earth originated from a single, simple life form billions of years ago. But what if that life did not originate on Earth? In this episode we'll explore the theory of Panspermia, that origin of life might be extraterrestrial in origin, and that the abiogenesis of that origin life form we descend from might have descended from the sky in a comet or some other alien source.

The faint, ephemeral glow emanating from the planetary nebula ESO 577-24 persists for only a short time -- around 10,000 years, a blink of an eye in astronomical terms. ESO’s Very Large Telescope captured this shell of glowing ionised gas -- the last breath of the dying star whose simmering remains are visible at the heart of this image. As the gaseous shell of this planetary nebula expands and grows dimmer, it will slowly disappear from sight.

When a white dwarf in a binary star system acquires more material than it can handle it creates a violent outburst of surplus gas. With this outburst the white dwarf attempts to correct the imbalance. Channelled by the magnetic field of the star, the ejecta take the form of spectacular symmetric jets extending hundreds of billions of kilometres from the white dwarf’s polar regions.

This animation shows the artist’s impression of a vampiric star. The red giant in this system is slowly expelling its outer layers into space. Here the second star in the system, a white dwarf, is siphoning this material into a disc surrounding it. The material then spirals down from this disc onto the white dwarf. Occasionally, more material will fall onto the white dwarf than it can handle. When this occurs, a violent outburst of surplus gas from the white dwarf attempts to correct the imbalance. Channelled by the magnetic field of the star, the ejecta take the form of spectacular symmetric jets extending hundreds of billions of kilometres from the white dwarf’s polar regions.

Already in 1810 astronomers discovered that the brightness of the star R Aquarii periodically changes and it has subsequently been found to vary with a period of approximately a year. During these cycles, R Aquarii has been seen to fade into obscurity and then become so bright as to almost be visible to the naked eye. This animation is an artistic representation of this change in brightness. More information and download options: http://www.eso.org/public/videos/eso1840g/ Credit: ESO/M. Kornmesser

This zoom video starts with a wide view of the Milky Way and ends with a close-up look at the chaotic and fascinating binary star system R Aquarii. The image shown in this final image of this video is data from the SPHERE/ZIMPOL instrument on ESO’s Very Large Telescope (VLT), and shows the binary star itself, as well as the jets of material spewing from the interacting stellar couple.

This video shows the evolution of a chaotic and fascinating binary star system named R Aquarii. The time lapse begins with observations from the Nordic Optical Telescope taken in 1997. In the 15 years since that image was taken the system has been observed by many other telescopes, including ESO’s Very Large Telescope. This video lapses between a selection of these images, showing the expansion and evolution of the material surrounding R Aquarii. R Aquarii is a so-called “symbiotic binary”, comprising two stars surrounded by a large, dynamic cloud of gas (a nebula). Systems like this contain two stars in an unequal and complex relationship. R Aquarii is made up of one hot white dwarf and one red giant. The red giant is losing matter to its small companion and occasionally ejecting matter in weird spurts, loops and trails, forming the intriguing shapes seen here. There is a lot going on between the performers in this cosmic double act. The red giant is a variable star, with a brightness that changes by a factor of 750 every year and three weeks. The faint nebula is named Cederblad 211 and is thought to be the result of a violent nova 250 years ago. Also visible is a narrow, vertical, S-shaped feature, with blobs of superheated material.

While testing a new subsystem on the SPHERE planet-hunting instrument on ESO’s Very Large telescope, astronomers were able to capture dramatic details of the turbulent stellar relationship in the binary star R Aquarii with unprecedented clarity — even compared to observations from Hubble.

Thanks to the hardworking Gaia spacecraft, astronomers think they’ve located a star that formed from the same solar nebula as the Sun. In fact, this star is a virtual twin of the Sun and it’s actually pretty close. Well, astronomical speaking.

From their laboratories on a rocky planet dwarfed by the vastness of space, Clemson University scientist Marco Ajello and his team have managed to measure all of the starlight ever produced throughout the history of the observable universe.

A star system in our galaxy could give us a ringside seat for one of the brightest lightshows in the universe. And, with luck, it won’t wipe out all life on our planet. The system—located 8000 light-years away and dubbed Apep after an Egyptian snake deity—contains a binary pair of stars surrounded by a serpentine-shaped dust cloud. One of stars is an unusually massive sun known as a Wolf-Rayet star. When such stars run out of fuel, they collapse, causing a supernova explosion. https://www.sciencemag.org/news/2018/11/massive-star-system-primed-intense-explosion http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Scientists studying what amounts to a computer-simulated "pulsar in a box" are gaining a more detailed understanding of the complex, high-energy environment around spinning neutron stars, also called pulsars. The model traces the paths of charged particles in magnetic and electric fields near the neutron star, revealing behaviors that may help explain how pulsars emit gamma-ray and radio pulses with ultraprecise timing. A pulsar is the crushed core of a massive star that exploded as a supernova. The core is so compressed that more mass than the Sun's squeezes into a ball no wider than Manhattan Island in New York City. This process also revvs up its rotation and strengthens its magnetic and electric fields. Various physical processes ensure that most of the particles around a pulsar are either electrons or their antimatter counterparts, positrons. To trace the behavior and energies of these particles, the researchers used a comparatively new type of pulsar model called a "particle in cell" (PIC) simulation. The PIC technique lets scientists explore the pulsar from first principles, starting with a spinning, magnetized neutron star. The computer code injects electrons and positrons at the pulsar's surface and tracks how they interact with the electric and magnetic fields. It's computationally intensive because the particle motions affect the fields and the fields affect the particles, and everything is moving near the speed of light. The simulation shows that most of the electrons tend to race outward from the magnetic poles. Some medium-energy electrons scatter wildly, even heading back to the pulsar. The positrons, on the other hand, mostly flow out at lower latitudes, forming a relatively thin structure called the current sheet. In fact, the highest-energy positrons here -- less than 0.1 percent of the total -- are capable of producing gamma rays similar to those detected by NASA's Fermi Gamma-ray Space Telescope, which has discovered 216 gamma-ray pulsars. The simulation ran on the Discover supercomputer at NASA's Center for Climate Simulation at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and the Pleiades supercomputer at NASA's Ames Research Center in Silicon Valley, California. The model actually tracks "macroparticles," each of which represents many trillions of electrons or positrons.

According to Gizmodo, scientists now believe Black Holes might temporarily be able to bring dead stars back to life. In what has been described as a “brief zombie awakening,” a team of scientists studying white dwarfs - small dense objects formed when bigger stars run out of fuel - determined that black holes could theoretically reignite dead stars in a supernova like explosion. Scientist went on to say that the results of reigniting these dead stars would be the generation and release of heavier elements into the cosmos. https://gizmodo.com/black-holes-might-temporarily-bring-dead-stars-back-to-1828715319 http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

The answer lies in the tiny shifts we see in a star's position as Earth revolves around the sun.

Ashes to Ashes, Dust to Dust: The Fate of Stars Like the Sun Greg Sloan of the Space Telescope Science Institute Our Sun, though seemingly eternal, is about halfway through its roughly 10-billion-year lifespan. What will happen when the Sun dies? Not only will the answer be important to whoever inhabits Earth in a few billion years, it is important to astronomers today. Quiet stars like the Sun are many times more numerous than large stars and play a major role in how galaxies develop. Importantly, how these stars die determines when life can first form in the galaxy.

Since 1937, astronomers have puzzled over the curious variability of a young star named RW Aur A, which is located about 450 light years from Earth. Every few decades, the star's optical light has faded briefly before brightening again. In recent years, astronomers have observed the star dimming more frequently, and for longer periods. Using NASA's Chandra X-ray Observatory, a team of scientists may have uncovered what caused the star's most recent dimming event: a collision of two infant planetary bodies. Once the planets were destroyed, the debris would have fallen onto the star, generating a thick veil of dust and gas. This would have temporarily obscured the star's light, explaining the dimming astronomers have seen. Computer simulations have long predicted that planets can fall into a young star, but scientists have never before observed that before now. If this most recent study is correct, it would be the first time that astronomers have directly observed a young star devouring a planet. Because the X-rays come from the hot outer atmosphere of the star, changes in the X-ray spectrum — the intensity of X-rays measured at different wavelengths — over these three observations were used to probe the density and composition of the absorbing material around the star. The team found that the dips in both optical and X-ray light are caused by dense gas obscuring the star's light. The observation in 2017 showed strong emission from iron atoms, indicating that the disk contained at least 10 times more iron than in the 2013 observation during a bright period. The researchers think the excess iron was created when two planetesimals, or infant planetary bodies, collided. If one or both planetary bodies are made partly of iron, their smash-up could release a large amount of iron into the star's disk and temporarily obscure its light as the material falls into the star. This discovery gives insight into the processes affecting the development of infant planets. Undoubtedly, astronomers will continue to study this fascinating object with Chandra and other telescopes.

For decades, astronomers have watched as the star RW Aur A has faded and brightened in optical light. RW Aur A is a few million years old and relatively close to Earth at a distance of 450 light years. Recently, they watched as the star dimmed more frequently and for longer periods of time. To investigate this mystery, a team of scientists used NASA's Chandra X-ray Observatory to study it using a different kind of light: X-rays. The X-rays provided evidence that the most recent dimming was caused by the destruction of a young planet that was then devoured by a star. This would be the first time that anyone has seen such an event and would help astronomers better understand how infant planets develop.

This sequence starts with a wide view of the Milky Way and zooms in on the globular star cluster NGC 6388 in the constellation of Scorpius (The Scorpion). The final images are first from MUSE on ESO's Very Large Telescope in Wide Field Mode and then the last, very sharp, image shows part of the cluster using the MUSE Narrow Field Mode with adaptive optics turned on.

The European Southern Observatory shared a particularly colorful image of the RCW 38 cluster, which contains a wealth of young and still-forming stars.

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

These three stars can easily be seen with the naked eye, but it took some fancy telescopes for us to realize how weird they really are!

Text in 'How far away is it - Supernovae and Star Clusters' document http://howfarawayisit.com/wp-content/uploads/2018/06/Star-Clusters-and-Supernova-v2-1.pdf Music free version - https://www.youtube.com/watch?v=U8h9uiwmKzg&list=PLpH1IDQEoE8QPoTrkKtAw01T2jbq623qs In this segment of our “How far away is it” video book, we cover Supernovae and star clusters. As we start Supernovae, we compare the magnitude of the exploding star that created the Helix Planetary Nebula with the explosion that created the Crab Nebula. We take the opportunity to describe the size and densities of White Dwarfs as compared to Neutron Stars. We also take a look at what the daytime sky might look like if Betelgeuse were to supernova. We then cover the Neutron Star that that a star supernova leaves behind. We take a deep look at the Crab Nebula’ Neutron star. We then take a look at the beautiful Veil Nebula and the Cygnus Loop. We then explain what a Type 1a Supernova is and how it works as a critically important standard candle. We show a binary star system with matter flowing through the L1 Lagrange point, and mention Subrahmanyan Chandrasekhar’s solution to Einstein’s equations. We then take a look at the amazing remnants of past supernova explosions scattered across our galaxy including: SN 1006, RCW 86, Tycho Supernova SN 1572, Cassiopeia A with its Light Echoes, RCW 103 with its Magnetar, Kepler's supernova SN 1604, N 63A, and Supernova 1987A. For RCW 103, we illustrate the impact on the Earth if it were Capella that went supernova. We conclude this section on SN with a look at how we find them with transient facilities like the Zwicky Transient Facility at the Palomar Observatory. We continue on to Star Clusters by pointing out that there are two primary kinds of star clusters: open cluster and globular cluster. We visit some very beautiful open clusters including: the Pleiades, the Jewel Box (NGC 4755), Pismis 24 in NGC 6357, Terzan 5, NGC 6791, and the Quintuplet and Arches clusters. And then we visit some spectacular globular clusters including: 47 Tucanae, Omega Centauri, Terzan 5, M30 and M53. We conclude by adding brightest globular clusters and Type 1a Supernova as key standard candle rungs on our distance ladder.
