Mass loss from very young massive stars (Mitteilungen der Universitäts‐Sternwarte zu Jena Nr. 172)

Abstract

A very important property of very young and massive stars (BN objects) is their intensive mass loss. We describe the main methods to derive the mass loss rates. Available observations are used to characterize the ionized stellar winds and the CO flows. The results are confronted with theories describing the anisotropic mass loss.
