mass loss

The loss of mass by a star during its evolution by one or more processes. Mass is lost at a high rate in bipolar outflows during the formation of a star, and as a T Tauri wind from some protostars. Mass is known to flow slowly into space from many stars, especially giants, in the form of a stellar wind. Mass can also be ejected as the shell of a planetary nebula or in a violent supernova explosion. Mass transfer can occur in close binary stars, and mass can be lost from the binary in a nova explosion.
