The evolutionary status of young stellar mass loss driving sources asderived from IRAS observations.
Abstract
A statistical analysis of the IRAS data for young stellar objects associated with mass outflows (Herbig-Haro objects and molecular outflows) is presented. Systematic differences are found between the observed far-infrared behavior and that predicted by a model describing the main accretion phase during the formation of low-mass stars. It is suggested that the low-mass outflow sources are at a later evolutionary stage and not truly protostellar.
