We discuss the evolutionary properties of shell burning star models which, due to the erosion of the external hydrogen envelope, leave the Hayashi track and evolve to the blue of the HR diagram. We analyze the properties of star models which evolve off the Asymptotic Giant Branch (AGB), the Early-AGB or the Red Giant Branch (RGB).
