Theory Seminar: Snow and the Seven Thousand White Dwarfs
Speaker: Jeremy Heyl, UBC
Location: Auditorium
Time: 13:00
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.
