RAS -- New supercomputer simulations may help explain periodic bursts of light emitted by compact binary star systems. Cataclysmic variables are binary systems that consist of a white dwarf and a normal star. The dense white dwarf drags material from its companion star, creating an accretion disc of matter around itself, and a hotspot develops where the gas stream from the star crashes into the accretion disc. On Wednesday 6th April at the RAS National Astronomy Meeting in Birmingham, Dr...

Cataclysmic Variable Star -- Cataclysmic variables are a class of binary stars containing a white dwarf and a companion star. The companion star is usually a red dwarf, although in some cases it is another white dwarf or a slightly evolved star (subgiant). Several hundreds of cataclysmic variables are known. From the observational viewpoint, cataclysmic variables are relatively easy to discover. They are usually quite blue objects, as the majority of stars are red. The variability of...
