SN 2010lp-a Type Ia Supernova from a Violent Merger of Two Carbon-Oxygen White Dwarfs
SN 2010lp is a subluminous Type Ia supernova (SN Ia) with slowly evolving lightcurves. Moreover, it is the only subluminous SN Ia observed so far that shows narrow emission lines of [O i] in late-time spectra, indicating unburned oxygen close to the center of the ejecta. Most explosion models for SNe Ia cannot explain the narrow [O i] emission. Here, we present hydrodynamic explosion and radiative transfer calculations showing that the violent merger of two carbon–oxygen white dwarfs of 0.9...[Show more]
