Mass loss rates of Li‐rich AGB/RGB stars

Abstract

A sample of AGB/RGB stars with an excess of Li abundances is considered in order to estimate their mass loss rates. Our method is based on a correlation between the Li abundances and the stellar luminosity, using a modified version of Reimers formula. We have adopted a calibration on the basis of an empirical correlation between the mass loss rate and some stellar parameters. We conclude that most Li‐rich stars have lower mass loss rates compared with the majority of AGB/RGB stars, which show no evidence of Li enhancements, so the Li enrichment process is apparently not associated with an increased mass loss rate.
