Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and ...

A newly discovered white dwarf star (right) is only slightly larger than the moon (left). Giuseppe Parisi Astronomers have discovered the smallest white dwarf star ever documented around 130 ...

In their death throes, roughly 97 percent of all stars become a smoldering stellar zombie called a white dwarf, one of the densest objects in the cosmos. A newly discovered white dwarf is being hailed ...

The smallest white dwarf star ever found is about the same size as Earth’s moon, but more massive than the sun. It appears to be shrinking, which could lead to a colossal explosion. Ilaria Caiazzo at ...

Only a smidge bigger than the moon, a newfound white dwarf is the smallest of its kind known. The white dwarf, a type of remnant left behind when certain stars peter out, has a radius of about 2,100 ...

Telescope observations have confirmed a weird property of white dwarf stars: As they pack on more mass, they shrink in size. White dwarfs, the stripped cores of dead stars, are thought to have this ...

(THE CONVERSATION) The Sun will someday die. This will happen when it runs out of hydrogen fuel in its core and can no longer produce energy through nuclear fusion as it does now. The death of the Sun ...

Astronomers find an explanation for the fastest stars in the galaxy while uncovering a new mechanism for a supernova explosion. Credit: Technion illustration Astronomers call a special kind of ...

White dwarfs are giving up more of their secrets, with the discovery that the hotter they are, the puffier their outer layers ...
