Evidence for energizing of Hα emission in type II supernovae by ejecta-wind interaction
Description
A simple one-zone model of Hα luminosity of late time type II supernovae, energized by 56Co-56Fe decay, was applied to the analysis of the observed Hα evolution. Of the six available SNeII with known Hα fluxes at late times, three reveal the extra Hα flux above the radioactive model. This excess is interpreted as an effect of an energy release due to ejecta-wind interaction. Two SNeII, 1979C and 1987F, with the particularly strong Hα excess, show additional spectroscopic signatures, which can be attributed to the dense wind around supernovae. (author)
