Numerical simulation of the three-dimensional structure and dynamics of the non-magnetic solar chromosphere
Sven Wedemeyer, Bernd Freytag, Matthias Steffen +2
Three-dimensional numerical simulations with CO5BOLD, a new radiation hydrodynamics code, result in a dynamic, thermally bifurcated model of the non-magnetic chromosphere of the qu…
Spectroscopic Analyses of the Blue Hook Stars in NGC 2808: A More Stringent Test of the Late Hot Flasher Scenario
S. Moehler, A. V. Sweigart, W. B. Landsman +2
Recent UV observations of the globular cluster NGC2808 (Brown et al. 2001) show a significant population of hot stars fainter than the zero-age horizontal branch (``blue hook'' sta…
Physical Processes in Star-Gas Systems
R. Spurzem, P. Berczik, G. Hensler +4
First we present a recently developed 3D chemodynamical code for galaxy evolution from the K**2 collaboration. It follows the evolution of all components of a galaxy such as dark m…
Evidence for a fundamental stellar upper mass limit from clustered star formation
Carsten Weidner, Pavel Kroupa
The observed masses of the most massive stars do not surpass about 150Msun. This may either be a fundamental upper mass limit which is defined by the physics of massive stars and/o…
Helium-rich EHB Stars in Globular Clusters
S. Moehler, A. V. Sweigart, W. B. Landsman +1
Recent UV observations of the most massive Galactic globular clusters show a significant population of hot stars below the zero-age HB (``blue hook'' stars), which cannot be explai…
Binaries discovered by the SPY project. III. HE2209-1444: a massive, short period double degenerate
C. A. Karl, R. Napiwotzki, G. Nelemans +4
In the course of our search for double degenerate (DD) binaries as potential progenitors of type Ia supernovae with the UVES spectrograph at the ESO VLT (ESO SN Ia Progenitor surve…
