The first double-burst supernova ever observed, SNR 0509, is a historic discovery that reveals how white dwarfs explode in ...

New model explains how inspiraling dead stars can explode at a rate high enough to match the number of Type Ia supernovae seen in universe A new mathematical model created by astrophysicists at the ...

Old binary star systems may contain stars that are even hotter than scientists previously believed. White dwarfs are the dense, compact remains left behind when stars exhaust their nuclear fuel, a ...

White dwarfs are the compact remnants of stars that have stopped nuclear burning, a fate that will eventually befall our sun.

The tides are changing for white dwarfs Old stars in binary systems may be even hotter than previously thought. (Nanowerk ...

A new study from Kyoto University has shown that white dwarfs, can be significantly hotter than expected when locked in tight ...

The surviving white dwarf would travel at thousands of miles a second; such “hypervelocity white dwarfs” would theoretically be all over the galaxy. According to Shen’s idea, if the majority of type ...

Astronomers have found a remarkable pair of stars that may finally prove a long-debated theory. Described in the journal Nature Astronomy, this duo offers the strongest evidence yet that type 1a ...

Cambridge, Ma – Astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have found that a supernova discovered last year was caused by two colliding white dwarf stars. The white dwarfs ...

A strange and violent fate awaits a white dwarf star that wanders too close to a moderately massive black hole. According to a new study, the black hole’s gravitational pull on the white dwarf would ...

Type Ia supernovae represent the dramatic thermonuclear explosions of white dwarf stars, typically triggered in binary systems by processes such as accretion from a companion or the merger of two ...
