An international team of astronomers has performed X-ray, ultraviolet, and optical observations of an X-ray source known as 1RXS J165424.6-433758. Results of the observational campaign, published June 8 on the pre-print server ...
A group of space scientists from the University of Southern Queensland, the University of Victoria, the University of Warwick and the Kavli Institute for Astrophysics and Space Research discovered a white dwarf star that ...
An international team of astronomers has analyzed the data from the latest phase of the Sloan Digital Sky Survey (SDSS). They discovered eight new cataclysmic variables (CV) systems. The finding is reported in a paper published ...
When stars like our sun die, they tend to go out with a whimper and not a bang—unless they happen to be part of a binary (two) star system that could give rise to a supernova explosion.
