Superbursts are very energetic explosions occurring at the outer crusts of neutron stars, as a consequence of unstable carbon burning . They release up to $10^{40}$ erg in a span of hours/days and have recurrence times in the order of years. In contrast to the standard, less-energetic bursts due to H/He burning, only a few multi-zone simulations have been reported. While these pioneering works...

1. Low mass density deflagration burning led to premature type Iax supernovae

The progenitor systems of normal type Ia supernovae (SNe Ia) remain a central puzzle. The long-debated single-degenerate (SD) channel, where a white dwarf (WD) accretes mass from a companion, faces major observational conflicts. The unknown rising form the carbon ignition and detonation mechanism in sub-Chandrasekhar mass led us to run 3D hydrodynamic simulations that address these tensions by...
