This book on star clusters addresses students as well as researchers i n
astrophysics. It contains two pedagogically written surveys which ma ke
the book well suited for class work. B. Carney presents our current
knowledge of the relative and absolute ages of globular clusters and
probes of the galaxy's chronology. He also studies their chemical hist
ory and what they reveal about the complexity of stellar evolution. W.
E. Harris studies globular cluster systems as subpopulations of one ga
laxy's stars. He also addresses their role in deriving a mass profile
for the Milky Way halo and what their luminosity distribution function
tells us about the Hubble constant.
