VLTI observations of AGB stars
M. Wittkowski, D. A. Boboltz, T. Driebe +1
We report on recent observations of AGB stars obtained with the VLT Interferometer (VLTI). We illustrate in general the potential of interferometric measurements to study stellar a…
A quasi-time-dependent radiative transfer model of OH104.9+2.4
D. Riechers, Y. Balega, T. Driebe +4
We investigate the pulsation-phase dependent properties of the circumstellar dust shell (CDS) of the OH/IR star OH104.9+2.4 based on radiative transfer modeling (RTM) using the cod…
High-resolution near-infrared speckle interferometry and radiative transfer modeling of the OH/IR star OH 104.9+2.4
D. Riechers, Y. Balega, T. Driebe +3
We present near-infrared speckle interferometry of the OH/IR star OH 104.9+2.4 in the K' band obtained with the 6m telescope of the Special Astrophysical Observatory (SAO). At a wa…
The evolution of helium white dwarfs: III. On the ages of millisecond pulsar systems
D. Schoenberner, T. Driebe, T. Bloecker
We employed recently computed evolutionary white-dwarf models with helium cores, supplemented by heavier models with carbon-oxygen cores, in order to investigate the ages of millis…
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…
