  Recent observations of white dwarfs in globular clusters indicate that these
stars may get a velocity kick during their time as giants. This velocity kick
could originate naturally if the mass loss while on the asymptotic giant branch
is slightly asymmetric. The kicks may be large enough to dramatically change
the radial distribution of young white dwarfs, giving them larger energies than
other stars in the cluster. As these energetic white dwarfs travel through the
cluster they can impart their excess energy on the other stars in the cluster.
This new heat source for globular clusters is expected to be largest during the
clusters' youth.
