SN 2006jc is a peculiar supernova (SN), in which the formation of dust has been confirmed at an early epoch of ∼50 days after the explosion. We investigate the possibility of such an earlier formation of dust grains in the expanding ejecta of SN 2006jc, applying the Type Ib SN model that is developed to reproduce the observed light curve. We find that the rapid decrease of the gas temperature i...
