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