... Spherical Accretion onto a Magnetic Dipole: Numerical Simulations" . ... Stationary flow was found in simulation of spherical accretion onto a non-rotating dipole. Dependences of the flow geometry (for example, position of the equatorial Alfven point) and of the integral properties (such as accretion rate) on the system parameters were established. Accretion rate onto dipole is always smaller than accretion rate onto corresponding star without magnetic field. ...

Radio-loud, Radio-quiet: quasars that look virtually identical at all other wavelengths can differ by a 1000 in their radio emission. Radio-loud quasars have a powerful jet moving at relativistic speeds (i.e. close to the speed of light) made up of energetic particles, themselves moving near the speed of light in a magnetic field. ...

Fundamental parameters and time evolution of mass loss are investigated for post-main-sequence stars in the Galactic globular cluster 47 Tucanae (NGC 104). ... We confirm the cluster's distance as d = 4611+213 -200 pc and age as 12 ТБ 1 Gyr. Horizontal branch models appear to confirm that no more red giant branch mass loss occurs in 47 Tuc than in the more metal-poor Я? Centauri, though difficulties arise due to inconsistencies between the models. ...

Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

Next: Introduction . ... A spike immunity method of digital integrating radiometer signals in the jamming environment is described. ... The purpose of the method is real-time signal processing, and the basic is an alternative selection of the least offset signal estimation using nonparametric "Nearest Neighbor" rule. ... The additive spike-like jam makes the "tails" of the distribution "heavier" which leads to different offsets for linear and rank mean estimation on the integrating interval. ...

... correaltor dump time) * (number of cycles per integration) The smaller you make this number (albeit you aren't allowed to go below 1ms) the larger your data file will be. So, if you are in a RFI-free frequency range, you may want to set your integration time to as much as 60s. However, if you are in a zone often affected by RFI, you may want to set this to be a much smaller values, say, 1s. koneil@naic.edu ...

... Appropriate values of DIT the integration time (DIT secs) for each individual integration, are lmited by various considerations. N.B. Ndit individual Integration s each of DIT secs are coadded to form a single Exposure of time Ndit*DIT].
