Abstract:

Virtually every star drives a supersonic wind which collides with interstellar gas or the wind of a companion star, resulting in luminous shock waves. These stellar wind bow shocks have been observed for young massive stars, high speed pulsars, and runaway stars. I will present the mathematical description of these bubbles emphasizing the conservation laws that permit analytic solutions (in steady-state) or relatively simple evolutionary models. For the majority of the talk, the mathematics assumed is a basic familiarity with vectors and calculus.
