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 ...

White dwarfs are the final stop for stars that aren’t massive enough to go out in a supernova. Think of them as the ...

White dwarfs, the compact remnants of low- to intermediate-mass stars, offer a unique window into the fate of planetary systems. Recent observational and theoretical work has revealed that many white ...

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 ...

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 ...

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 ...

White dwarfs are the stars that will be left behind when stars like the sun "die," smoldering away in space as cooling stellar embers. Recent observations indicated that some of these stellar corpses ...
