White Dwarfs, Star Clusters, and the Lives and Deaths of Stars

Nearly all stars will end their lives as white dwarf stars. Studying white dwarf stars in star clusters is particularly valuable for probing a variety of astrophysically interesting questions, including the ages of stars. Star clusters are a good approximation of an essentially pure stellar populations due to the coeval formation of member stars out of the same parent cloud. In this talk I will discuss ongoing work of using the white dwarfs in star clusters and what they can tell us about white dwarf formation and cooling, and stellar evolution as a whole.
