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 team of astronomers have found that planet formation in our young Solar System started much earlier than previously thought, with the building blocks of planets growing at the same time as their ...

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 ...
When stars run out of fuel and come to the end of their lives, the biggest ones explode in huge supernovas. But smaller stars go through a different change in which they throw off portions of their ...
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 ...
ASTRONOMERS have spotted a stunning cosmic butterfly with glowing “wings” deep in space. The mind-blowing display is actually ...
For the first time, researchers have found a way to describe conditions deep in the convection zone of “white dwarf” stars, which are home to some of the densest collections of matter in the Universe.
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 ...
All sky view of the Milky Way taken by the European Space Agency's Gaia space observatory. Open any astronomy textbook to the section on white dwarf stars and you’ll likely learn that they are “dead ...
(Nanowerk News) 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 are white dwarfs. As stars reach the end ...
