Nebular Spectra of 111 Type Ia Supernovae Disfavor Single Degenerate Progenitors

M. A. Tucker, B. J. Shappee, P. J. Vallely +15

We place statistical constraints on Type Ia supernova (SN Ia) progenitors using 227 nebular phase spectra of 111 SNe Ia. We find no evidence of stripped companion emission in any o…
