Blank Sky But Not Blank Information

Archival data are able to place constraints on the origin of supernova 2011fe.

A New Pulsating, Magnetic, Carbon Atmosphere White Dwarf

The authors present the discovery of a new hot carbon-atmosphere white dwarf with a strong magnetic field. This discovery might help illuminate the origins of a recently found class of white dwarfs.

Perils of a Cooling Host Star: Life on planets around white and brown dwarfs

The holy grail for exoplanet science would be to find an inhabited planet. Not just habitable, but actually inhabited. But where are we most likely to find those planets? Only around Sun-like stars, or could life thrive around other types of stars? Could evolved stars like white dwarfs or neutron stars harbor life? Could brown dwarfs, the so-called failed stars, have inhabited planets?

Observational Signatures of Accretion Induced Collapse of White Dwarfs

A massive white dwarf accreting from a companion can lead to accretion induced collapse turning the white dwarf into a neutron star – how can such an event be observed?

Asteroid vs. White Dwarf

What happens when an asteroid and a white dwarf (WD) meet? The asteroid doesn’t get the better end of the deal — and the WD might end up with a brand new debris disk.
