Astronomers have investigated a nearby cataclysmic variable system known as CTCV J2056-3014 using ESA's XMM-Newton satellite. Results of the study, presented in a paper published July 28 on the arXiv pre-print repository, ...
At the heart of every white dwarf star—the dense stellar object that remains after a star has burned away its fuel reserve of gases as it nears the end of its life cycle—lies a quantum conundrum: as white dwarfs add mass, ...

German astronomers have conducted photometric observations of a cataclysmic variable (CV) star known as PTF1J2224+17. Results of the observational campaign confirm that this object is a polar, as suggested by previous studies. ...
Astronomers have peered into the home galaxies of fast radio bursts, ruling out supermassive black holes as a cause and bringing us a step closer to understanding the origins of these mysterious signals from outer space.
