Sion and Greenstein developed a classification system for these objects based on the presence ofHe I, He II, and metal lines.
Sion and Greenstein developed a classification system for these objects based on the presence ofHe I, He II, and metal lines. Kanaan and Metcalfe determined that, in line with theoretical arguments,one of these objects had heavily crystallized as it cooled. If these objects can strip mass from acompanion, they can undergo carbon detonation followed by a (*) type Ia supernova. Stars that haveinsufficient mass to form a red giant will shed their outer layers to form one of these objects. They aresupported entirely by electron degeneracy pressure and therefore have to be smaller than 1.44 solarmasses. For 10 points, name these dense stars that have mass less than the Chandrasekhar Limit.
