Thermodynamical properties of stellar matter: II. Internal energy, temperature and density exponents and specific heats for stellar interiors
W. Stolzmann, T. Bloecker
Starting from the Helmholtz free energy we calculate analytically first- and second-order derivatives, as internal energy and specific heats, for the ideal system and the exchange…
The Evolution of Helium White Dwarfs: Applications to Millisecond Pulsars
T. Driebe, T. Bloecker, D. Schoenberner
We present a grid of evolutionary tracks for low-mass white dwarfs with helium cores in the mass range from 0.179 to 0.414 M_sun. The lower mass limit is well suited for comparison…
The evolution of helium white dwarfs: II. Thermal instabilities
T. Driebe, T. Bloecker, D. Schoenberner +1
We calculated a grid of evolutionary models for white dwarfs with helium cores (He-WDs) and investigated the occurrence of hydrogen-shell flashes due to unstable hydrogen burning v…
Evolutionary Models of White Dwarfs with Helium Cores
T. Driebe, D. Schoenberner, T. Bloecker +1
We present seven evolutionary tracks for low-mass white dwarfs with helium cores, ranging in mass from 0.179 to 0.414 Msol. We generated the pre-white dwarf models from a 1 Msol se…
The role of convective boundaries
F. Herwig, T. Bloecker, D. Schoenberner
We investigate the influence of convective overshoot on stellar evolution models of the thermal pulse AGB phase with M_ZAMS = 3 Msol. An exponential diffusive overshoot algorithm i…
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…
