High resolution in z-direction: The simulation of disc-bulge-halo galaxies using the particle-mesh code SUPERBOX
R. Bien, A. Just, P. Berczik +1
SUPERBOX is known as a very efficient particle-mesh code with highly-resolving sub-grids. Nevertheless, the height of a typical galactic disc is small compared to the size of the w…
The main sequence from F to K stars of the solar neighbourhood in SDSS colours
A. Just, H. Jahreiss
For an understanding of Galactic stellar populations in the SDSS filter system well defined stellar samples are needed. The nearby stars provide a complete stellar sample represent…
Dynamical friction in flattened systems: A numerical test of Binney's approach
Jorge Penarrubia, Andreas Just, Pavel Kroupa
We carry out a set of self-consistent N-body calculations to investigate how important the velocity anisotropy in non-spherical dark-matter haloes is for dynamical friction. For th…
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…
Stability and evolution of super-massive stars (SMS)
Andreas Just, Pau Amaro-Seoane
Highly condensed gaseous objects with masses larger than 5x10^4 M_sun are called super-massive stars. In the quasistationary contraction phase, the hydrostatic equilibrium is deter…
Super-massive stars: Radiative transfer
Pau Amaro-Seoane, Rainer Spurzem, Andreas Just
The concept of central super-massive stars (, where is the mass of the super-massive star) embedded in dense stellar systems was su…
