Regular stars collapse and die once they run out of fuel for their nuclear reactions, but the white dwarfs just sit there, hanging out, for eternity.

University of Warwick astronomers have uncovered compelling evidence that a nearby white dwarf is in fact the remnant of two stars merging—a rare stellar discovery revealed through Hubble Space ...

"If you were able to stand somewhat close to the white dwarf's pole, you would see a column of gas stretching 2,000 miles ...

This small carbon trace marks this object as a product of a rare white dwarf merger rather than single‑star evolution. In a paper published in Nature Astronomy, Snehalata Sahu (University of Warwick) ...

Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...

Astro Brief is a collaboration between KSMU, the Missouri Space Grant, and MSU's Department of Physics, Astronomy and ...

A study of supernova remnant SNR 0519-69.0 using the Chandra X-ray telescope, Hubble and more has narrowed down its age to ...

White dwarf stars represent the evolutionary endpoints of medium- and low-mass stars, comprising the dense, electron-degenerate cores left after nuclear fuel exhaustion. In binary systems, ...

Curious about the supermassive black hole at the center of our galaxy? Wondering what will happen when the Sun’s core collapses, forming a white dwarf? Explore these fascinating phenomena during this ...

Scientists have discovered two rare white dwarfs—which are among the dimmest stars in the universe—that feature changes in their surface composition caused by magnetic fields. This brings the number ...
