Supernova Explosions Inside Pre-existing Wind-Driven Cavities: Spherically Symmetric Models
This paper presents some preliminary results on the evolution of supernova explosions propagating inside wind-driven bubbles. The hydrodynamic simulations are performed with a Lagrangian one dimensional code and include the evolution of a strong stellar wind from the Type II supernova progenitor. This wind, with M = 10-5 M⊙ yr-1 and V = 103 kms-1, creates a large and expanding interstellar bubble with a massive outer shell. The SN ejecta evolve in the complex density distribution of the bubble and generate a series of reflected shock waves as the blast wave encounters different density stratifications.
