Type Ibn Supernova SN 2010al: Powerful Mass Loss Half Year Prior to the Explosion
Type Ibn supernova SN 2010al is explored to infer parameters of supernova and a circumstellar (CS) shell. The CS interaction model combined with the spectral model of 4600 Å blend suggests the explosion of a WR star with the energy of \((1{-}1.5)\times 10^{51}\) erg inside a dense confined CS shell with the mass of \({\sim}0.1M_{\odot}\) and kinetic energy of \({\sim}10^{48}\) erg. The confined CS shell has been formed during the last 0.4 yr prior to the core collapse.
