A rare white dwarf merger remnant emerges in ultraviolet light, revealing thin layers of hydrogen and helium stripped away during a cosmic collision. Scientists at the University of Warwick report the ...

Astronomers have discovered the "missing link" connecting the death of sunlike stars to the birth of white dwarf stellar remnants, in the form of a "teenage vampire" white dwarf. This vampire isn't ...

A white dwarf star locked in a tight dance with its stellar companion is undergoing one of the most extreme cases of stellar cannibalism ever observed. According to a new study published in the ...

Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can ...

In an ancient star system expected to be stable and dormant, scientists found a 3 billion-year-old white dwarf star still tearing apart massive quantities of rock. “The rate we’ve seen rock consumed ...

A smaller white dwarf star (left) pulls material from a larger star into a swirling accretion disk. The pair is called an “intermediate polar,” and MIT astronomers used powerful telescopes to measure ...
