| Abstract: |
In this paper we present 3D simulations of the gravitationally confined detonation (GCD) model of Type Ia Supernovae with multiple ignition points as initial conditions. These simulations release more energy during the deflagration (subsonic nuclear combustion) phase than previous GCD simulations initiated with a single ignition point. Due to the increased amount of fuel consumed during the deflagration, the star undergoes a more energetic pulsation which at the time of detonation increases the amount of low-density, intermediate-mass-producing material and decreases the amount of high-density, NSE-producing material. This results in the production of approximately 0.7 M⊙ of 56Ni in the explosion, an amount that observations indicate is produced in Type Ia supernovae having typical luminosities. |
