Binary star evolution
WebBSE is a rapid binary star evolution code. It can model circularization of eccentric orbits and synchronization of stellar rotation with the orbital motion owing to tidal interaction in detail. Angular momentum loss mechanisms, such as gravitational radiation and magnetic braking, are also modelled. Wind accretion, where the secondary may ...

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 ...
