... 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. ...

But associating the current exoplanet properties with their formation epoch can be problematic, since the formation process is intimately associated with the physical conditions associated with their birthplaces: the disks of gas and dust that orbit young stars. ...

... Finding Stars . ... Handling Bad Pixels . ... The guide camera image controller can control one or more guide cameras. ... Each time the camera is read, the image is automatically saved to a fits file on a shared disk. ... Cameras that have bad pixels require "bad pixel maps" in order to find stars, centroid or even compute statistics for the image. ... View this image (for instance in NIH Image) and determine an upper and lower cutoff; pixels whose values are outside of this range are considered...

... 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. ...

Microsymposium 38, MS083, 2003 (A4 format) MERCURY: LOCAL VARIATIONS OF THE PHOTOMETRIC RELIEF. ... Because of trajectory and pointing angle constraints the planet could be observed from Mariner 10 only over a small range of phase angles between about 75o and 110o. Therefore the photometric investigations are restricted to measuring the distribution of brightness on the Mercurian 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. ...
