Understanding these mergers helps explain binary star fates and potential progenitors of thermonuclear supernovae. The six known DAQ type white dwarfs exhibit log (C/H) > –0.5 and appear in optical ...

University of Warwick astronomers have discovered an extremely rare, high-mass, compact binary star system only ~150 light years away. These two stars are on a collision course to explode as a type 1a ...

In this picture, we capture the binary in the moment where the first white dwarf has just exploded, hurtling material towards its nearby companion which is on the cusp of explosion too. This event ...
