Numerical Studies of Supernova Evolution in Circumstellar Wind-Blown Nebulae
Vikram Dwarkadas ( U Chicago) - April 14 at 12:00 noon
We discuss various aspects of the interaction of supernova remnants
(SNRs) with the ambient medium. In particular we focus on the
evolution of SNRs in environments sculpted by the progenitor star, and
summarize the various factors that affect the dynamics, kinematics and
radiation signatures of the remnant. As a specific example, we
consider the evolution of the medium around a 35 solar mass
star. Using numerical hydrodynamics simulations we study the
interaction of the shock wave with this medium when the star explodes
as a SN. The evolution of the SN shock wave in this case may have a
bearing on other SNRs evolving in wind-blown bubbles, such as SN
1987A.
The seminar will be held in 501 Campbell Hall.
