Meinunger (1966) classified it as an eclipsing binary with a period very close to 1 day, noting however that the period and derived minima times were uncertain due to the low variability amplitude. As of July 2011, the O C gateway (Paschke Brat 2006; Paschke 2009) lists, in addition to Meinunger's photographic data, 2 visual and 3 CCD times of minima from Paschke (1988, 1996, 2006), Stepan (1995), Br t et al. ...

The ION experiment flown on the Interball-Aurora mission performs simultaneous ion and electron measurements. Two mass spectrometers looking in opposing directions perpendicular to the satellite spin axis, which points toward the sun, measure ions in the mass and energy ranges 1-32 amu and ~ 0 to 14,000 eV. ...

... Here we discuss our survey methods, identification procedure and first results. Our survey is found to be efficient at finding flat-spectrum radio-loud quasars (FSRQs, 59 of our first 85 IDs) and BL Lacertae objects (22 of our first 85 IDs), a figure which is comparable to or greater than that achieved by other radio and X-ray survey techniques. ... Particularly important is the identification of a large population of FSRQs ( of DXRBS FSRQs) with ratios of X-ray to radio luminosity . ... FSRQs . ...

Next: The Model Up: No Title Previous: Radiopulsars as Sources of . In this section, we study the evolution of stellar populations on a time-scale of 10 Myr for a starburst љ occurring under conditions similar to those in the Galactic Center (see Lipunov et al. (1995d)[ 126 ]). We estimate the expected number of X-ray transient љ sources (NS + MS star), super accreting BH, and BH + supergiant binaries, all as functions of time elapsed after the burst. ...
