Avoiding a (thermonuclear) supernova
Discovery of a circumstellar nebula with a hot central star – product of a white dwarf merger?
Tiny Stars in a Tiny Orbit: A New Ultracompact Binary
The discovery of the record-setting 38 minute orbit of IGR J17062-6143 makes it the fastest known accreting milllisecond pulsar orbiting in binary system!
Hunting for Variable White Dwarfs in the GALEX Archives
What secrets are hiding in the archives of the GALEX satellite?
How Many Planets Will We Find Around White Dwarfs?
We know that white dwarfs have planets, but there are very few that we have detected directly. An upcoming survey may change that.
Gravitational Redshift and the Pup: Measuring the Mass of Sirius B
Measuring a white dwarf’s gravitational redshift can help us figure out its mass, but for one of the closest stars to us (Sirius B) the numbers didn’t match with other methods. Today’s paper investigates the discrepancy.
Seeing Red (and Blue): Two Sub-Populations of Type Ia Supernovae?
A close examination of thirteen Type Ia supernovae in the earliest days after their initial explosion reveals two distinct sub-populations.
