| Abstract: | Motivated by a recent discovery of Supernova 2010gx and numerical results of Fryer et al.(2010), we simulate light curves for several type I supernova models, enshrouded by dense circumstellar shells, or "super-wind", rich in carbon and oxygen and having no hydrogen. We demonstrate that the most luminous events like SN2010gx can be explained by those models at moderate explosion energies 2-3 foe if the total mass of SN ejecta and a shell is 3-5 Msun and the radius of the shell is ~10^{16} cm. |
