Title: Type Ia Supernovae and Heavy Metals From Dark Matter

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.
