A speeding, superdense neutron star somehow got a powerful "kick" that is propelling it completely out of our Milky Way Galaxy into the cold vastness of intergalactic space. Its discovery is puzzling astronomers who used the National Science Foundation's Very Long Baseline Array (VLBA)...
Title: Discovery of the longest-period rapidly oscillating Ap star HD177765 Authors: D. Alentiev, O. Kochukhov, T. Ryabchikova, M. Cunha, V. Tsymbal, W. Weiss We present the discovery of a long-period, rapidly oscillating Ap star, HD177765. Using high-resolution time-series observations o...
Title: A Search for Superhumps in the Cataclysmic Variable SW Sextantis Authors: Gerald D. Rude II, F. A. Ringwald We present differential photometry of the cataclysmic variable star SW Sextantis. A time series analysis was performed in search of superhumps in the accretion disk of this star, whi...
Space Exploration Technologies (SpaceX) and Space Communication Ltd. (Spacecom) of Ramat-Gan Israel, operator of the AMOS satellite fleet, have signed an agreement for launch of a communication satellite aboard a SpaceX Falcon 9 as early as December 2012. Falcon 9 will insert the satellite int...
Meteor scatter occurs when a signal bounces off a meteor's ionised trail. When a meteor strikes earth's atmosphere, a cylindrical region of free electrons is formed at the height of the E layer. This slender, ionised column is relatively long, and when first formed is sufficiently dense to reflect...
