Astronomers using the Hubble Space Telescope have discovered a "ultra-massive white dwarf that formed when a white dwarf ...

For the first time, astronomers have discovered evidence for a giant planet orbiting a tiny, dead white dwarf star. And, surprisingly, the Neptune-sized planet is more than four times the diameter of ...

An old white dwarf, LSPM J0207+3331, 145 light-years away, is still consuming metal-rich planetary debris.

The future of yellow dwarf stars, like our sun, is determined almost entirely by their mass. The most massive stars, about eight to 12 times heftier than the sun, can explode as supernovae, leading to ...

In about 7 billion years our sun will become a white dwarf, the name for a star that depleted its nuclear fuel and only shines as a remnant of what it once was. No star is ever born as a white dwarf ...

Astronomers have discovered the smallest yet most massive white dwarf star ever seen. According to a new study published Thursday in the journal Nature, the "very special" star has a mass greater than ...

Astronomers have discovered the smallest but most massive white dwarf ever found. The tiny star is only the size of our Moon, but packs in more mass than the Sun, meaning it’s approaching 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 ...

Astronomers have spotted a white dwarf that miraculously survived its own thermonuclear detonation, raising questions over how and why these stars create supernovas. A white dwarf is the evolutionary ...

In general, it's very difficult to have a star transform into a white dwarf and wind up with a planet very close in orbit around it without that planet being destroyed by a tidal disruption event. A ...
