| Abstract |
In binaries consisting of two massive stars, strong stellar winds from these stars collide each other. Shocked regions produced by the wind-wind collision is thought to be a place where not only the particle acceleration and resulting high-energy emission but also the dust formation take place. Studying the wind-wind collision shocks is thus of multi-facet importance. Numerical simulations suit it very well, given that massive binaries, in general, have large orbital eccentricities. In this talk, I will report on the structure of the wind-wind collision shocks in two massive binaries, eta Carinae and WR 140, obtained from 3-D numerical simulations. |
