| Résumé : | To explain observations of overluminous Type Ia supernovae, strongly magnetized white dwarfs with masses above 2 solar masses have been proposed as their progenitors. This has interesting implications in high-precision cosmology, as Type Ia supernovae have been widely used as standard candles. We compute equilibrium configurations of magnetized white dwarfs, self-consistently determining the structure of a compact object in strong (poloidal) magnetic fields. Our results show that, although the magnetic field can support indeed these massive configurations, they might never be reached in nature since electron capture destabilizes the star already at lower masses. Hence strongly magnetized white dwarfs are unlikely to be the progenitors of overluminous supernovae. |
