The Pleiades is one of the most well-known open clusters visible with the naked eye from Earth. But just how far away is the cluster? New results help determine a more accurate distance and suggest a troubling error in a previous study.
The number and luminosity distribution of white dwarfs stars can be used to help figure out the past history of the Galactic halo.
What might be causing the accretion rates in newly formed stars to remain so high?
In today’s Astrophysical Classic, we hark back to 1987 and the introduction of a new method determining the age of the universe through the use of white dwarf stars.
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.
