The Evolution of Supernovae in Circumstellar Wind Bubbles II: Case of a Wolf-Rayet star

Understand

(Abridged) Mass-loss from massive stars leads to the formation of circumstellar wind-blown bubbles surrounding the star, bordered by a dense shell.

• When the star ends its life in a supernova (SN) explosion, the resulting shock wave will interact with this modified medium.
• In a previous paper we discussed the basic parameters of this interaction.
• In this paper we go a step further and study the evolution of SNe in the wind blown bubble formed by a 35 $\msun$ star that starts off as an O star, goes through a red supergiant phase, and ends its life as a Wolf-Rayet star.
