Type Ia Supernova Progenitors: Ripple in Still Water
Carles Badenes
University of Pittsburgh
Despite years of continuing efforts, the nature of the progenitors of
Type Ia Supernovae remains obscure. I will review the state of the art
in this field, and highlight some recent observational advances that
might be hinting - finally! - at a solution. In particular, I will
describe how new data mining techniques applied to the spectroscopic
data base from the Sloan Digital Sky Survey have allowed us to measure
the merging rate of binary White Dwarfs in the Milky Way. This rate
happens to be very close to the Type Ia supernova rate in SBc spirals.
