The kinematic dispersions of disc stars can be used to measure the dynamic contributions of baryons to the rotation curves of spiral galaxies and hence to trace the amount and distribution of the remaining dark matter. However, the simple single-comp

We present a description of a reusable software package able to control a large, heterogeneous network of fully and semi-robotic observatories initially developed to run the MONET network of two 1.2m telescopes. Special attention is given to the desi

The “MOnitoring NEtwork of Telescopes” (MONET) consists of two 1.2-m imaging telescopes funded by the Alfried Krupp von Bohlen und Halbach Foundation and the Georg-August-Universitat Gottingen and will be operated by the McDonald Observatory in W

The fully convective secondary stars in short-period CVs are rapidly rotating and thus should have a characteristic global magnetic field produced by an α-Dynamo. This field is expected to be dipole-like, with an axis lying in the orbital plane, and

We study numerically the interaction of the infalling gas stream and the rim of the accretion disc in cataclysmic variables. The simulations were performed with a smoothed particle hydrodynamics scheme with high spatial resolution. Parameters of the

The tomographic method Physical Parameter Eclipse Mapping is a tool to reconstruct spatial distributions of physical parameters (like temperatures and surface densities) in accretion discs of cataclysmic variables. After summarizing the method, we ap

We consider the effects of accretion stream overflow on the viscous dynamics of accretion discs in dwarf novae. If the stream from the secondary star is geometrically thick enough, some fraction of its material can flow over and under the disc. The m
