Mass-losing Red Giants in Open Clusters
Abstract
The author has searched for mass-losing stars in open clusters with main-sequence turn-offs at intermediate mass by using the IRAS data base. The absence of many strong 60 μm sources in open clusters implies that intermediate-mass stars lose much of their mass during an intense wind phase of rather short duration. For stars of masses ≡7 M_sun;, this phase, if it exists at all, lasts for not much more than 105yr. For stars of ≡4 M_sun;, the intense wind phase appears to last considerably less than 107yr; it may well last for less than 106yr.
