Abstract
SN 2006jc is an intriguing and unusual core-collapse supernova. Using optical and
J, H, and K band spectroscopy, we intend to test if the Helium-rich
circumstellar environment of this peculiar SN is very dense, n~10^10
cm^-3, and it therefore must have been lost by the progenitor star before
explosion. This would support the progenitor channel for envelope-stripped
SN where a massive star strips its outer layers by strong winds. We
furthermore would like to test if molecule formation is taking place in
the SN ejecta, along with dust formation.
