We present the results of the development of Sternberg Astronomical Institute Catalog Access Services (SAI CAS) project - the first and the only project in Russia, which provides online access to the major astronomical catalogues and different services on top of them. ... SAI CAS is an open-source implementation of the general Catalogue access service (influenced by SDSS CAS & CASjobs project), based on original algorithms and open-source software. ...

... October 2, 1999 . Phi Persei: Double Star . ... Based on recent results , this artist's vision of the double star Phi Persei , 720 light years away, shows a bright, rapidly rotating massive star surrounded by a disk of gas. A small companion star orbits 100 million miles away. ... Ten million years ago the small companion was actually the most massive star in the system and because of its greater mass evolved into a giant star more quickly. ... About APOD > . ...

THE 75th NAME-LIST OF VARIABLE STARS. ... The 75th Name-List consists of two tables. ... the literature, taken from positional catalogues, including USNO A1.0/A2.0 and GSC, or determined by the authors); the range of variability (sometimes the column Min gives, in parentheses, the amplitude of light variation; the symbol ( means that the star , in minimum light, becomes fainter, than the magnitude indicated); and the system of magnitudes used ( P are photographic ...

... The distance scales of the objects are matched both by comparing the first derivatives of the angular velocity determined separately from radial velocities and proper motions and by the statistical-parallax method. ... Good agreement between the inferred 0 and our calculations based on space velocities suggests that the Lindblad relation holds throughout the entire sample volume. ... Brandt and Blitz (1993) published the distances and radial velocities for a total of 206 H II-regions. ... Astron. ...
