The progenitor mass of the Type IIP supernova SN 2004et from late-time spectral modeling

Abstract:

SN 2004et is one of the nearest and best-observed Type IIP supernovae, with a progenitor detection as well as good photometric and spectroscopic observational coverage well into the nebular phase. Based on nucleosynthesis from stellar evolution/explosion models we apply spectral modeling to analyze its 140-700 day evolution from ultraviolet to mid-infrared. We find a M ZAMS = 15 M âŠ(tm) progenitor star (with an oxygen mass of 0.8 M âŠ(tm)) to satisfactorily reproduce [Oâ‰i] λλ6300, 6364 and ...
