Sub-chandrasekhar progenitors favoured for type ia supernovae: evidence from late-time spectroscopy

HIGHLIGHTS

  • who: MNRAS and colleagues from the Southern Observatory, Karl-Schwarzschild-Straße, Garching bei München, Germany , Unidad Mixta Internacional Franco-Chilena de Astronomı́a, CNRS/INSU UMI , and Instituto de Astrofı́sica, Pontificia Universidad Católica de have published the paper: Sub-Chandrasekhar progenitors favoured for Type Ia supernovae: evidence from late-time spectroscopy, in the Journal: (JOURNAL)
  • what: Using the evolution of the Fe II 12 570 -7155 Å line as a prior in fits of spectra covering only the optical wavelengths the authors show that the 7200 Å feature is fully explained by_[Fe . . .
