However, this track is only valid for a certain mass. The figure above, from the Wikipedia Hayashi Track entry, shows representative PMS evolutionary tracks for different masses

WebThe shape and position of the Hayashi track on the Hertzsprung–Russell diagram depends on the star's mass and chemical composition. For solar-mass stars, the track lies at a temperature of roughly 4000 K. Stars on the track are nearly fully convective and have their opacity dominated by hydrogen ions.
