Type Ia Supernova Explosion : Gravitationally Confined Detonation

  title={Type Ia Supernova Explosion : Gravitationally Confined Detonation},
  author={Alan C. Calder and Don Q. Lamb},
We present a new mechanism for Type Ia supernova explosions in massive white dwarfs. The proposed scenario follows from relaxing the assumption of symmetry in the model and involves a detonation created in an unconfined environment. The explosion begins with an essentially central ignition of stellar material initiating a deflagration. This deflagration results in the formation of a buoyantly-driven bubble of hot material that reaches the stellar surface at supersonic speeds. The bubble… CONTINUE READING
