H- and He-burning central stars and the evolution to white dwarfs
T. Bloecker
The structure and evolution of central stars of planetary nebulae (CSPNe) is reviewed. CSPNe represent the rapid transitional stage between the Asymptotic Giant Branch (AGB) and th…
The dynamical evolution of the fragmented, bipolar dust shell around the carbon star IRC +10216: Rapid changes of a PPN-like structure?
R. Osterbart, Y. Balega, T. Bloecker +2
We present high-resolution J-, H-, and K-band observations and the first H-K color image of the carbon star IRC +10216. The images were reconstructed from 6m telescope speckle inte…
The dynamical evolution of the dust shell of IRC+10216
R. Osterbart, Y. Balega, T. Bloecker +2
We present high-resolution J-, H-, and K-band observations of the carbon star IRC+10216. The images were reconstructed from 6 m telescope speckle interferograms using the bispectru…
AGB evolution with overshoot: hot bottom burning and dredge up
T. Bloecker, F. Herwig, T. Driebe
We calculated models of massive AGB stars with a self-consistent coupling of time-dependent mixing and nuclear burning for 30 isotopes and 74 reactions. Overshoot with an exponenti…
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…
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…
