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 ...

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 ...

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 ...

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 ...

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 ...

About 8,150 light-years from Earth, a white dwarf star named Gaia22ayj has intrigued astronomers. Its unusual behavior, characterized by extreme pulsations, has led to a major discovery about the life ...

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 ...

German astronomers have discovered a new type of star, and exactly how these weird white dwarfs came to be remains a mystery. The stars are covered in a layer of “ash” that’s usually produced by ...
