Two Clusters and White Dwarfs

Astronomers compare the cooling stars in two massive globular clusters, M13 and M3, to study the evolution of white dwarfs. These two clusters are about the same age and have roughly the same percentage of elements heavier than helium, but their populations of the kind of stars which will end their lives as white dwarfs are different. Thus, M13 and M3 form a natural laboratory the lives pf white dwarfs.
