"The large volume of data from Rubin will give us a sample of all kinds of Type Ia supernovas at a range of distances and in ...

White dwarfs are among the most compact objects in the cosmos, though not as dense as a black hole. Stars with up to eight times the mass of our sun appear destined to end up as a white dwarf.

The white dwarf, or dead star, in question is the compact companion of the star HD 49798, which is located around 1,700 light-years away from Earth with a mass around 1.5 times that of the sun.

When we first began searching for planets around other stars, one of the surprising discoveries was that there are planets orbiting white dwarfs. The first exoplanets we ever discovered were white ...

The most plausible outcome is this brazen white dwarf (the spent core of a sun-like star), which is about one-tenth the mass of our sun. It's shedding its dense, outer layer and triggering these ...

Black holes themselves emit no light, but the supermassive black holes at the centers of galaxies are often surrounded by huge clouds of material. It's this material, heated by friction and gravity as ...

Now, researchers report that they have caught a supermassive black hole in the act of eating a white dwarf, the last stage of evolution for stars like our Sun – but the white dwarf is not giving ...

Triple-star systems are about 10% of the sun-like star population. But being able to put together this evolutionary history is challenging." Hubble observed the white dwarf companion star that the ...
