A hypervelocity white dwarf might be left over from a Type Ia supernova. Today’s paper studies the white dwarf in detail.
How does habitability vary on a galactic scale?
A white dwarf binary system that sometimes shows evidence of a magnetic field — but only some of the time.
A peculiar X-ray binary may contain the first known white dwarf which is still in the process of contracting.
Today’s paper discusses a recent, unusual supernova, which may be the first strong evidence for a long-predicted phenomenon: an exploding white dwarf triggered by an initial explosion in its atmosphere.
