Progenitor mass of the type IIP supernova 2005cs.

UTROBIN V.P. and CHUGAI N.N.

Abstract (from CDS):

The progenitor mass of type IIP supernova can be determined from either hydrodynamic modeling of the event or pre-explosion observations. To compare these approaches, we determine parameters of the sub-luminous supernova 2005cs and estimate its progenitor mass. We compute the hydrodynamic models of the supernova to describe its light curves and expansion velocity data. We estimate a presupernova mass of 17.3±1M, an explosion energy of (4.1±0.3)x1050erg, a presupernova radius of 600±140R, and a radioactive 56Ni mass of 0.0082±0.0016M. The derived progenitor mass of SN 2005cs is 18.2±1M, which is in-between those of low-luminosity and normal type IIP supernovae. The obtained progenitor mass of SN 2005cs is higher than derived from pre-explosion images. The masses of four type IIP supernovae estimated by means of hydrodynamic modeling are systematically higher than the average progenitor mass for the 9-25M mass range. This result, if confirmed for a larger sample, would imply that a serious revision of the present-day view on the progenitors of type IIP supernovae is required.
