Sasdelli, Michele; Hillebrandt, Wolfgang; Kromer, M; Ishida, Émille E.O.; Röpke, Friedrich K.; Sim, Stuart; Pakmor, R; Seitenzahl, Ivo; Fink, M


Over the past years, Type Ia supernovae (SNe Ia) have become a major tool to determine the expansion history of the Universe, and considerable attention has been given to, both, observations and models of these events. However, until now, their progenitors are not known. The observed diversity of light curves and spectra seems to point at different progenitor channels and explosion mechanisms. Here, we present a new way to compare model predictions with observations in a systematic way. Our...[Show more]
