Early Lightcurves of Type Ia Supernovae Are Consistent with Nondegenerate Progenitor Companions

If Type Ia supernovae (SNe Ia) result from a white dwarf being ignited by Roche-lobe overflow from a nondegenerate companion, then as the SN explosion runs into the companion star its ejecta will be shocked, causing an early blue excess in the lightcurve. A handful of these excesses have been found...
