The hydrodynamical structure of circumstellar envelopes around low mass-loss rate, low outflow velocity AGB stars.

Abstract (from CDS):

Recent hydrodynamical models (Winters et al. 2000b) allow the existence of pulsating, large velocity amplitude Asymptotic Giant Branch (AGB) stars with tenuous dusty circumstellar shells, which produce low mass-loss rates and simultaneously low wind velocities. The Semi-regular long-period variable L2 Pup shows a broad SiO maser feature at 86GHz (v=1, J=2-1), indicating an outward velocity of the material close to the stellar photosphere of at least 10km/s, and narrow CO (J=2-1) and (1-0) line profiles indicating an outflow velocity of the material in the circumstellar shell of only about 3km/s. This can be explained in terms of our hydrodynamical models which provide large velocities in the shocked stellar atmosphere and low velocities of the circumstellar outflow.
