A massive white dwarf star with a bizarre carbon-rich atmosphere could be two white dwarfs merged together according to an international team led by University of Warwick astronomers, and only ...

Astronomers may have finally solved the mystery of how superdense dead stars called white dwarfs keep their heavy metal shells fresh — by cannibalizing what remains of their planetary systems. White ...

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

Illustration depicting the hot stellar merger that formed the ultra-massive white dwarf -WD 0525+526. (Dr. Snehalata Sahu/University of Warwick) (CN) — Astronomers at the University of Warwick have ...

Astronomers have traced the origin of a colossal white dwarf to a catastrophic crash between two dead stars, turning a quiet stellar ember into a cosmic heavyweight. Using the Hubble Space Telescope, ...

"When we saw the results, it actually fitted this long-standing question of how these hypervelocity white dwarfs formed. It was super cool." When you purchase through links on our site, we may earn an ...

Astronomers have discovered the smallest and most massive white dwarf ever seen. The smoldering cinder, which formed when two less massive white dwarfs merged, is heavy, “packing a mass greater than ...

Astronomers have found a white dwarf star with a strange metallic scar on its surface. This blemish probably formed when the star ripped up and ate a small planet in its orbit. Researchers often spot ...

Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after ...
