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 ...
NASA’s IXPE has become the first observatory to measure a white dwarf star. It used its X-Ray polarization to reveal 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 ...
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 ...
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 ...
The identification of J1912-4410 marks only the second discovery of a white dwarf pulsar, a rare type of celestial object emitting pulsed radiation. This system features a rapidly rotating white dwarf ...

What old, dying stars teach us about axions as a candidate for dark matter
In recent years, astronomers have become increasingly interested in a theoretical particle known as the axion, which was ...
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 ...
The discovery of a rare type of white dwarf star system provides new understanding into stellar evolution. The discovery of a rare type of white dwarf star system provides new understanding into ...
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 ...
