Latest Variable star Stories
Two Dallas high school students discovered five stars as members of an SMU summer physics research program that enabled them to analyze data gleaned from a high-powered telescope in the New Mexico desert.
A recent nova, located in the constellation Delphinus, is the brightest such event since 2007 and is visible with the naked eye, assuming the observer is in a relatively dark location away from city lights.
Astronomers have discovered that the brightness of the remnant of a stellar collision can vary in a way that scientists have not observed before.
Astronomers writing in the journal Astronomy & Astrophysics say they have discovered a new type of variable star by measuring minute variations in stellar brightness.
The study of the 'demon star,' Algol, made by a research group of the University of Helsinki, Finland, has received both scientific and public attention
Astronomers from the California Institute of Technology (Caltech) and the University of Arizona have released the largest data set ever collected that documents the brightening and dimming of stars and other celestial objects—two hundred million in total.
An otherwise nondescript binary star system in the Whirlpool Galaxy has brought astronomers tantalizingly close to their goal of observing a star just before it goes supernova.
Researchers have discovered 122 new eclipsing binary stars and observed hundreds more variable stars in an innovative survey using NASA's two STEREO solar satellites.
Astronomers have turned up the first direct proof that "standard candles" used to illuminate the size of the universe, termed Cepheids, shrink in mass, making them not quite as standard as once thought.
Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...
