What are white dwarfs? (Astronomy)

White dwarfs are dead stars that continue to glow because of heat, not nuclear fusion. Most stars in our universe will end up as a white dwarf star. Join us to learn how white dwarfs are made, what they’re like, how long they’ll shine, and how astronomers detect them. ⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫ We highly recommend the Astronomy textbook “Universe” by Roger Freedman et al: Universe 9th Edition http://amzn.to/2so6Ums Universe 10th Edition http://amzn.to/2tfBjUe Shop Amazon Used Textbooks - Save up to 90% http://amzn.to/2pllk4B ⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫ Be sure to subscribe so you don't miss videos from Socratica! http://bit.ly/1ixuu9W And please share with all your friends!

What are neutron stars? (Astronomy)

What are neutron stars?  (Astronomy)

Stars are not eternal and unchanging - they are born, live their lives, and then die. The way a star dies depends on its mass. A low mass star ends as a white dwarf. A high mass star becomes a black hole. But in between, a star becomes a neutron star. In this video we talk about which stars become neutron stars, and the physics behind their formation. ⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫ We highly recommend the Astronomy textbook “Universe” by Roger Freedman et al: Universe 9th Edition http://amzn.to/2so6Ums Universe 10th Edition http://amzn.to/2tfBjUe Shop Amazon Used Textbooks - Save up to 90% http://amzn.to/2pllk4B ⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫ Be sure to subscribe so you don't miss videos from Socratica! http://bit.ly/1ixuu9W And please share with all your friends!

Universe Documentary 2017 | White Dwarf - Universe's Sleeping Monster | National Geographic A white dwarf, also called a degenerate dwarf, is a stellar core remnant composed mostly of electron-degenerate matter. A white dwarf is very dense: its mass is comparable to that of the Sun, while its volume is comparable to that of Earth. A white dwarf's faint luminosity comes from the emission of stored thermal energy; no fusion takes place in a white dwarf wherein mass is converted to energy. The nearest known white dwarf is Sirius B, at 8.6 light years, the smaller component of the Sirius binary star. There are currently thought to be eight white dwarfs among the hundred star systems nearest the Sun. The unusual faintness of white dwarfs was first recognized in 1910. The name white dwarf was coined by Willem Luyten in 1922. The universe has not existed long enough to experience a white dwarf releasing all of its energy as it will take many billions of years

The Last Light Before Eternal Darkness – White Dwarfs & Black Dwarfs

The Last Light Before Eternal Darkness – White Dwarfs & Black Dwarfs

Everything will end. Even the universe. But in a future so far away that it defies description, there will still be light and therefore a chance for life. It will be around White Dwarfs, the corpses of stars. But even they will fade one day..
