What happens when a high-mass (more than 4 solar masses) Main Sequence\nstars runs out of Hydrogen in its core. At first the internal evolution\nlooks like that of a low-mass star, but now we get first a Red Supergiant\nthen a sucession of blue and red supergiant phases as different nuclear\nfuels are tapped by the star for its energy. This lecture describes\nthe evolution of high-mass stars from the Main Sequence until their\neventual ends.\nRecorded 2006 January 27 in 1008 Evans Laboratory on the Columbus campus\nof The Ohio State University.
