Document Summary
The discussion divides up neatly into three categories; low-mass stars, intermediate-mass stars, and high-mass stars. Stars that vary their luminosity in time in a regular or an irregular fashion. White dwarfs are: burned out cores of low-mass stars. Supernovae are: explosions of stars on mass greater than 10 mo at the end of their existence as a result of a rapid collapse of their cores. The rotating neutron star remnant of an exploded star. Black holes are: matter that has been compressed to a radius such that nothing can escape from it, even light. Globular clusters are quite different from the irregular (or open) galactic clusters they exist in a completely different region of our galaxy, 12-14 many giant stars are found in groups called global clusters, named fro their sphericial shapes. A typical global cluster may be figure 12. 29 may contain up to a million stars in volume 200 light years across.
