A unified formula for mass-loss rate of O to M stars

Abstract

A formula for stellar mass-loss rate has been derived using conservation equations of mass and momentum for coronal and continuum radiation-driven wind. The derived mass-loss rate formula has been found to be consistent with the observed mass-loss rates for stars from O to M spectral type. Two constant parameters appearing in the mass-loss rate formula have been found to have values for special group of stars such as Be-stars, which are different from the majority of stars.
