Theory Seminar (High Energy/Cosmology)
Type Ia Supernovae and Heavy Metals From Dark Matter
Date: Tuesday, March 29th
Time: 3:30 pm
Place: 5280 Chamberlin Hall
Speaker: Joseph Bramante, University of Notre Dame
Abstract: Recent studies of low-redshift type Ia supernovae indicate
that at least half explode from sub-Chandrasekhar mass progenitor
white dwarfs. This talk explains how asymmetric dark matter would
ignite white dwarfs, and form star-destroying black holes inside old
neutron stars inhabiting regions densely populated with dark matter.
Links between dark matter and the anomalously high heavy metal
abundance of Reticulum II will also be discussed.
