I argue that the observational evidence for white dwarf-white dwarf mergers supports the view that they give rise to ultra-massive white dwarfs or neutron stars through accretion induced collapse. The implications for the progenitors of Type Ia SNe are discussed.

Resumen

Resumen

Se argumenta que la evidencia observacional de fusiones enana blanca enana blanca apoya el punto de vista de que dichos procesos producen enanas blancas ultra-masivas о estrellas de neutrones, mediante colapso inducido por acreción. Se discuten las implicaciones para las progenitoras de SNe tipo Ia.
