While astronomers have observed white dwarfs consuming companion stars on numerous occasions, for the first time, they have now observed the consumption of the companion’s helium and not just hydrogen.
Researchers use data from ESA’s Gaia telescope to discover that white dwarf stars have two different distributions both in how they move and how bright they shine.
By studying white dwarf stars, and finding some of them, well, in a way polluted, astronomers have found that most rocky exoplanets are made of rocks we can’t find anywhere in our Solar System.
Dr. Ken Shen talks about white dwarfs in interacting binary systems, with a focus on thermonuclear phenomena. And of course news update from Gaia, Mars Helicopter, comet Borisov and more.
White dwarfs are the final state of stars like our Sun at the end of their lives. Recently a Jupiter sized planet was discovered orbiting very close to a white dwarf. In this podcast, learn about this planet, its discovery and how it was studied using NASA and NOIRLab facilities.
Time for sky guide and news roundup with @AwesomeAstoPod. We have exoplanet in another galaxy, liquid water on Mars, exoplanet around white dwarf and the Sun get more active again.
Today, astronaut Terry Virts Tells Us “How To Astronaut” and news update! We have ultra-hot Neptune, extragalactic planet, and planet around white dwarf. #365DaysOfAstro
Supernova vs. White Dwarf: Who Wins? Will the CMB disappear one day? Why do comet tails curve? @PaulMattSutter will answer these questions at #365DaysOfAstro
White dwarfs are usually about 60% the mass of the Sun, so it was a bit of a surprise when astronomers found one that was almost exactly twice that. What happens when white dwarfs merge?
Is the Milky Way in a cosmic void? more update from astronomy this week!
