... Future seminars . P a s t seminars . Seminar council . Propeller Driven Jets and Spin-Down of Rotating Magnetized Stars " . ... We discuss axisymmetric MHD simulations of disk accretion to a rapidly rotating star with an aligned dipole magnetic field. The simulations reveal poverful disk winds and magnetically dominated collimated jets along the open field lines of the star. The star spins down rapidly under these sonditions. ...

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...

... Satellite data ] . SMIS ] . The program calculates the satellite orbit using ephemeris data in either predict-telegrams (APT predict, TBUS data) or 2-line NORAD format (TLE data). It determines the start and finish times of acquisition session and stores the data for antenna control during the receipt onto the hard disk. The program creates session schedules, supports selection of specific regions for observation and automatic filtration of satellite passes over the selected regions. ...
