Scientific paper

We find that carbon-oxygen cores in the mass range of about 1.05-1.25 Msolar, which ignite carbon off-center, may present an interesting SN Ia progenitor scenario, which could contribute to understanding the diversity of SNe Ia, since due to the small amount of carbon ignited, we get a whole range of central densities between 1-6×109 g cm-3, thus we expect various outcomes in terms of the velocities and composition of the ejecta.
