Location:  Auditorium          

Speaker:   Jeremy Heyl (UBC)

Title:     Snow and the Seven Thousand White Dwarfs

Abstract: Using the Hubble Space Telescope our group has build an unprecedented
sample of nearly seven thousand white dwarfs in the globular cluster 47
Tucanae.   I will describe how we use these white dwarfs to measure
dynamical relaxation in the core of the cluster, constrain the epoch of
mass loss in the post-main sequence evolution of solar-like stars, probe
the cross-section of neutrinos in the keV regime, constrain the properties
of the axion and of course see stars snowing.
