... Observations include: broad-band optical and near-infrared photometry, simultaneous optical and ultraviolet (IUE) spectroscopy, X-ray (Ginga) and radio (VLA) data. ... There is evidence for an enhanced H emission region visible near phase 0.250.35 which may be associated with a large spot on the primary and with two small optical flares which were also observed at other wavelengths: one in microwave radiation and the other in X-rays. ... Multiwavelength observations of YY Gem, 1988 March. ...

The revision of the MASS/DIMM star catalogue N. Shatsky, V. Kornilov March 16, 2008 Abstract The compilation of the (updated) version of the MASS (MASS/DIMM) device target catalogue is described. ... Then the list was cleaned according to following criteria: I. Remove stars too faint for a MASS device. ... Here the color equation of the Sternb erg device was taken: M AS S mag = V mag + 0.45 (B - V ); stars with M AS S mag > 3.2 were removed. ... This was made based on the GCVS4.2 catalogue data. ...
... Rig ht: the wavelength calibrated spectrum of the symbiotic star HBV 475 in 1969 and 1970, and of Nova Cygni 1970 in September 1970. ... With the aim of investigating the spectral evolution of HBV 475 following its novalike explosion, Kohoutek collected during 19691975 a set of OP plates centred on the position of the symbiotic star using 23в23 cm2 103aO, 103aD, and 103aE plates. ... Fig. 1 (right) shows the spectrum of HBV 475 in two epochs and of Nova Cygni 1970 just exploded. ...

The mean age of the stellar populations in the centers of all three galaxies has been found to be approximately the same, 1 Gyr. ... In contrast, in NGC 3166, there is a metallicity gradient, but the stellar age remains approximately constant up to a distance of 8 from the center. ...
