Charged polarized white dwarfs with finite temperature as a possible source of type Ia supernovae

We investigate the structure of polarized charged white dwarfs with finite temperature as a possible type Ia supernovae source. The white dwarf is modeled considering an isothermal core with central temperature 10(8) [K] and an envelope where the temperature distribution depends on the mass density. Regarding the fluid, we assume that it is composed of nucleons and electrons. The structure of the polarized charged white dwarfs is obtained by solving the Einstein-Maxwell equations with charge densities represented by two Gaussians, forming an electric dipole layer at the stellar surface. We obtain larger and more massive white dwarfs when polarized charge and the Gaussians width are increased. We find that to appreciate effects in the white dwarf's structure, the electric polarized charge must be in the order of 5.0 x 10(20)[C]. We obtain a maximum white dwarf mass of around 2.4M(circle dot) for a polarized charge of 1.5x10(21)[C]. This mass result can indicate that polarized charged white dwarfs are possible progenitors of superluminous type Ia supernovae. Furthermore, the mass-central density curves we obtain are very similar to the ones reached recently for ultra-magnetized white dwarfs.
