WebBinary Stars. The variety seen in double-star systems is nearly as rich as the galaxy’s stellar population as a whole. These pairs can differ significantly in mass, with, say, a mid-sized yellow star like our Sun locked in an orbital embrace with a far smaller, cooler red dwarf. Some binary partners evolve rapidly into red giant or supergiant ... WebIn Doppler's opinion they are binary stars. Such a star is usually invisible because it emits infrared instead of white light. In the orbit section with the maximal radial speed in the direction of Earth, the observed frequency on Earth is shifted from infrared to visible red. in affect in effect

For example, the two stars in Castor (called the ...

Two teams of astronomers, Daniel P. Whitmire and Albert A. Jackson IV, and Marc Davis, Piet Hut, and Richard A. Muller, independently published similar hypotheses to explain Raup and Sepkoski's extinction periodicity in the same issue of the journal Nature.
