STARS

As we become more experienced Observers, it is easy to become jaded by the stars. We use them as signposts and pointers to the “interesting” objects we have on our observing lists, and can begin to take the stars themselves for granted. It is only when we begin to understand stars and how important that they are, that we really begin to treat them as a significant part of our astronomy experience. Everything that you see in the night sky is visible to you because of light from a star. The stars themselves, nebulae, planets, moons, are visible because of starlight. Even dark nebulae are visible because they block the illumination of stars or other objects lit up by stars. Stars are born in clouds of cosmic gas and dust and provide light as a product of nuclear fusion. We exist because early generations of stars generated the elements that make up our planet and the chemical elements required for life. It is not an understatement to say that we exist because stars exist! As the author and coordinator of the Astronomical League Stellar Evolution program, Bill will explain the evolutionary paths of low and high mass stars. The League program guide includes a 27-page guide to stellar evolution, and a list of 100 objects to observe, many of which will be discussed in this fascinating presentation. Bio – Bill Pellerin was president of the Houston Astronomical Society in 2012-2013. As the author and coordinator of the ‘Stellar Evolution’ observing program for the Astronomical League. He has awarded 80 observers with a pin and certificate for completing the program (since 2013). He is the east Texas manager for the International Dark Sky Association, a member of the McDonald Observatory Board of Visitors and the American Association of Variable Star observers. He is currently active in observing R Crb type variable stars and reporting those observations to the AAVSO.

The constellation of Ophiuchus, which is represented as a serpent-bearer, contains a fascinating star called Barnard’s Star. It has a magnitude of 9.5 which renders it invisible to the unaided eye. In the past 100 years, scientists have collected fascinating data about this star, and have even discovered evidence of an exoplanet. Barnard’s star in one of the most studied red dwarfs because of its proximity to Earth, and its proper motion is the fastest recorded in the sky. 0:14 - Subscribe to Learn the Sky 0:38 - Intro to Barnard's Star 1:22 - Properties of Barnard's Star 2:55 - Proper Motion of Barnard's Star 3:28 - Barnard's Star b Planet 4:45 - Fast Facts about Barnard's Star 6:01 - Photo Attributes Photo Attributes: -Artist’s Conception of a planet orbiting a red dwarf star: By NASA, ESA and G.

Partial supernova blasts star across the Milky Way and we know about that thanks to NASA's Hubble Space Telescope. The star designated SDSS J1240+6710 managed to survive a “partial supernova” blasting itself out of its orbit with another star.

When the largest stars die, it’s usually pretty obvious. Supernovae are visible from billions of light-years away. But recently astronomers watched a massive star just disappear. No explosion, nothing, it just… vanished? Of course, it could have been dust. It’s always dust. But one intriguing possibility is that the star just imploded directly into a black hole, without the supernova detonation. And if that’s the case, is this happening more often, we just didn’t notice it? Want to see this video early?

Our solar system has just one star in it, the sun. But this is actually not the most common situation for systems. Most systems are multi-star systems, with binary systems being extremely common. These are systems where two stars orbit around their center of mass, and some of them even have planets. But we also know that stars come in so many varieties, due to their differing masses, and they leave behind different remnants. For this reason, there are a great many possible combinations of star types that produce different kinds of binary systems. What happens when you have a black hole and a main sequence star as a binary system? Or a pulsar and a red dwarf? How do the stars influence each others evolution? It's intense! Let's take a look.

T Tauri stars are less than 10 million years old. A star begins its life as a protostar still enveloped in its molecular cloud. Over the years the newborn star accretes new material from the surrounding area and develops a proto-planetary disc. Slowly, stellar winds and radiation blow away the gas and dust and when the surrounding shell is all cleared up, the star enters the T-Tauri phase.

All the stars we see in night sky one day they will use all of their energy and will be gone. But what happens before that depends upon their mass. Stars whose mass is 0-8 times of the sun they will swell and become red giant. As time passes, they will loose all the remaining energy and slowly fade away to darkness. Stars whose mass is 8 to 25 times the mass of Sun their core will collapses into themselves. That will result into Supernova explosion, Neutron Stars are born from these explosions. Stars that are more than 25 times massive than sun, first they will collapse into themselves but instead of exploding, they will become Black Holes. What Are The Effects of Full Moon on Humans?
