TP-AGB evolution with overshoot for low-mass stars as a function of metallicity
Falk Herwig, Thomas Bloecker, Thomas Driebe
We give a brief review on the properties of asymptotic giant branch models with overshoot. Then we describe new model calculations with overshoot. Initial masses are ranging from 1…

On the formation of hydrogen-deficient post-AGB stars
F. Herwig, T. Bloecker, N. Langer +1
We present an evolutionary sequence of a low mass star from the Asymptotic Giant Branch (AGB) through its post-AGB stage, during which its surface chemical composition changes from…

On the validity of the core-mass luminosity relation for TP-AGB stars with efficient dredge-up
F. Herwig, D. Schoenberner, T. Bloecker
We investigate the validity of the core mass - luminosity relation (CMLR), originally described by Paczynski (1970), for asymptotic giant branch stars under the presence of third d…
