Latest Cataclysmic variable star Stories
A team of Chinese astronomers have discovered a giant planet close to the exotic binary star system QS Virginis.
This week, Astronomy & Astrophysics publishes a somewhat unusual research article because it is co-authored by German high-school students.
Disks of hot gas that accumulate around a wide variety of astronomical objectsâ€”from degenerate stars in energetic binary systems to supermassive black holes at the hearts of active galaxiesâ€”are likely to be much larger than previously believed.
New Spitzer Space Telescope observations of an unusual class of interacting binary stars detected excess amounts of infrared radiation, suggesting that these odd objects are surrounded by large disks of cool dust.
Amateur astronomers are being asked to help a constellation of observatories unravel the mysteries of a puzzling binary star system.
New supercomputer simulations may help explain periodic bursts of light emitted by compact binary star systems.
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...
