ABSTRACT

Capella—the `Goat Star' in the constellation Auriga, the `Charioteer'—is the sixth brightest star in the sky, third in the Northern hemisphere. It is a well-known spectroscopic binary of yellow giants, appears to form a physical system with Capella HL, an outlying pair of RED DWARFS, and is a member of the extended Hyades MOVING GROUP (coeval with the nuclear region of the nearby young cluster).
