Carbon Monoxide in type II supernovae.

SPYROMILIO J., LEIBUNDGUT B. and GILMOZZI R.

Abstract (from CDS):

Infrared spectra of two type II supernovae 6 months after explosion are presented. The spectra exhibit a strong similarity to the observations of SN1987A and other type II SNe at comparable epochs. The continuum can be fitted with a cool black body and the hydrogen lines have emissivities that are approximately those of a Case B recombination spectrum. The data extend far enough into the thermal region to detect emission by the first overtone of carbon monoxide. The molecular emission is modeled and compared with that in the spectra of SN1987A. It is found that the flux in the CO first overtone is comparable to that found in SN1987A. We argue that Carbon Monoxide forms in the ejecta of all type II SNe during the first year after explosion.
