Single-degenerate type Ia supernovae without hydrogen contamination
S Justham - The Astrophysical Journal Letters, 2011 - iopscience.iop.org
The lack of hydrogen in spectra of type Ia supernovae (SNe Ia) is often seen as troublesome
for single-degenerate (SD) progenitor models. We argue that, since continued accretion of …
