Clouds of gas between spiral arms . ... In the region of galactic longitudes 60 - 74 degree, latitudes +-15 degree and distances from centres of Galaxy 11 - 12 kpc 81 HI clouds are found and their parameters (figure 1) are measured. ... Average concentration of gas within clouds is 0.15 -3 cm. The life time of the clouds with such concentration between spiral arms permits to evaluate the velocity of ionization and to choose model of heating interstellar matter satisfying to these data. ...

... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

... The zero point was derived in the following way: ffl Matching the OM repsonse using the measurements of BPM16274 and LBB227. ffl the zeropoints in U, B, V are set in a way that the simulations with the Vega spectrum (from ESO ftp server) matches the average brightness found in the literature which is (0.025, 0.03, 0.03) mag respectively. ffl In the UV filters the ESO Vega brightness is arbitrarily set to the U value, i.e. 0.025 mag ... The analysis comprised of the following steps: 1. ...

Irregular phenomena in the Earth Pole oscillation process and temporal variations of geopotential Valery Bondarenko, Vadim Perepelkin s The observed irregular phenomena in the Earth Pole oscillation process are very variety. ... These phenomena indicated in the IERS data are the "abnormal" fluctuation of the Earth Pole coordinates which owing to changing of the geodynamical parameters gives negative result in interpolation and forecast of the first approximation mathematical model. ... Fig. ...

... Curiously, the appearance of HS 0822+3542 is morphologically similar, on the same angular scales, to that of SBS 0335-052E (Melnick et al. ... The B -band SB profile (Fig. 5 ) indicates the presence of two components: the central bright compact body and an exponential disc, dominating the light in the outer part of the profile (hereafter LSB component). ... 1998 ]; Doublier et al. [ 1999a ]) shows that the scale length of HS 0822+3542 is smaller than that of any BCG studied in the cited works. ...
