Abstract: |
We explore one of the plausible causes of asymmetry in the wind of an AGB star: the presence of a binary companion. We have developed a simple method for estimating the intrinsic non-sphericity of the outflow in this case. Assuming the Roche model, local stellar parameters (Teff , g) are calculated, and then a formula for the local mass loss rate is applied. As a by-product a relation between the ratio of stellar radius to the Roche lobe radius and the overall wind enhancement is obtained. |
