Abstract

I analyse peculiar properties of light curve and continua of enigmatic Ibn supernovae, including SN 2006jc, and argue in favour of the early strong circumstellar interaction. This interaction explains the high luminosity and fast flux rise of SN 1999cq, while the cool dense shell (CDS) formed in shocked ejecta can explain the smooth early continuum of SN 2000er and unusual blue continuum of SN 2006jc. The dust is shown to condense in the CDS at about day 50. Monte Carlo modelling of the He i 7065 Å line profile affected by the dust occultation supports a picture, in which the dust resides in the fragmented CDS, whereas He i lines originate from circumstellar clouds shocked and fragmented in the forward shock wave.
