White dwarfs, the glowing cores of dead stars, often host disks of dusty debris. However, these debris disks only appear 10-20 millions of years following the star’s violent Red Giant phase. A new ...

A massive white dwarf star with a bizarre carbon-rich atmosphere could be two white dwarfs merged together according to an international team led by University of Warwick astronomers, and only ...

What can white dwarf stars eating their own planets teach astronomers about planetary and solar system formation and evolution? This is what a recent study published in The Astrophysical Journal hopes ...

Dead stars known as white dwarfs, have a mass like the sun while being similar in size to Earth. They are common in our galaxy, as 97% of stars will eventually become white dwarfs. As stars reach the ...

Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after ...

Astronomers have found a remarkable pair of stars that may finally prove a long-debated theory. Described in the journal Nature Astronomy, this duo offers the strongest evidence yet that type 1a ...

WASHINGTON (Reuters) -Astronomers using the Hubble Space Telescope have observed a white dwarf - a highly compact stellar ember - that appears to have gobbled up an icy world akin to the dwarf planet ...

Planetesimal orbits around a white dwarf. Initially, every planetesimal has a circular, prograde orbit. The kick forms an eccentric debris disk which with prograde (blue) and retrograde orbits (orange ...
