What can white dwarf stars eating their own planets teach astronomers about planetary and solar system formation and ...

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 ...

Astronomers have discovered a rare type of red dwarf star system, only the second of its kind to have been found. The discovery will help provide astronomers and scientists with a better understanding ...

"When we saw the results, it actually fitted this long-standing question of how these hypervelocity white dwarfs formed. It was super cool." White dwarfs — the superdense, slowly cooling embers left ...

The discovery of a rare type of white dwarf star system provides new understanding into stellar evolution. White dwarfs are small, dense stars typically the size of a planet. They are formed when a ...

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.

Astronomers have captured their second-ever glimpse into a rare celestial object: a white dwarf pulsar. Pulsars are typically envisioned as spinning neutron stars — a type of stellar remnant left by ...

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 ...

In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two-faced. One side of the white dwarf is composed of ...

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 ...
