Movie made by Inti Pelupessy from one of my hydro simulations of mass transfer in binaries.

Single AGB star (3 MSun) losing wind at constant rate of 1e-06 MSun/yr and constant velocity of 15 km/s.

Position of the AGB wind particles as they interact with the companion star (1.5 MSun).

Column density profile for a simulation of an AGB of 3 MSun losing mass at a constant rate of 1e-06 MSun/yr and wind velocity = 15 km/s. The companion star is a low mass star (1.5 MSun) orbiting at a distance of 3 AU in a circular orbit.
