The authors report the discovery of perhaps the faintest black hole x-ray binary. But this conclusion is limited by the uncertainty in the distance to the object.
Archival data are able to place constraints on the origin of supernova 2011fe.
I recently participated in an engineering trip to the SOAR Telescope in Chile, where I helped with numerous maintenance and upgrades for the Goodman Spectrograph.
Kepler finds a new binary system with a Delta Scuti pulsator.
In today’s paper, the authors study how the periods of two black hole x-ray binaries are changing. They find that the periods are decaying faster than expected based on standard theoretical arguments.
The progenitors of a special type of cataclysmic variable, AM CVn, and possibly supernovae have been found.
The authors seek to understand how two galaxies are interacting with each other.
The authors present the first direct evidence of a jet shaping the circumstellar envelope of a post-AGB star.
Lots and lots more data from the Sloan Digital Sky Survey.
