... astro-ph . ... Statistical Characterization of the Chandra Source Catalog . ... The first release of the Chandra Source Catalog (CSC) contains ~95,000 X-ray sources in a total area of ~0.75% of the entire sky, using data from ~3,900 separate ACIS observations of a multitude of different types of X-ray sources. ... In addition to these traditional catalog elements, for each X-ray source the CSC includes an extensive set of file-based data products that can be manipulated interactively. ...

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...

An atom is the smallest "piece" of an element that still has the properties of that element. For example, an atom of gold is the smallest piece of gold that still acts like gold ? ... When many atoms come together, atoms tend to form molecules. A molecule is a combination of two or more atoms bonded together. For example, a molecule of water (designated by the symbol H 2 O) consists of two hydrogen atoms and an oxygen atom which are in a "relationship" ? ...

Prague, August 16, 2006 . Our trial revision of the GCVS data for several southern constellations show that type changes are not needed for most stars. ... We suggest to add one more symbol combining types, in the cases when two or more classification options remain for the same star, for example, EC|Ell, EC|RR (here EC means a contact eclipsing binary, this is one of our suggestions from next slides). ... Moreover, it will simplify moving stars from the suspected-variable catalogue to the GCVS. ...

. Two neighboring stars did not pass each other without incident early in their lives. More than 4 billion years ago, our Sun got into a property battle with a wandering star. Each star ran off with some of the other's dust and debris. A mixture of indigenous and captured material resulted from the stellar squabble.
