Abstract

We review the various possibilities that have been proposed as progenitors of Type Ia supernovae (SNe Ia) from the point of view of binary evolution and population synthesis. Depending on the nature of the progenitor, there may be systematic effects that cannot be calibrated by local observations that could undermine their use as standard candles.
