Authors: V.A. Marsakov , Yu.G. Shevelev , . Journal: 1988, Astron Zh. ... Absolute magnitudes, metallicities, effective temperatures, surface gravities, distances, and tangential velocities are calculated for 5498 F stars with homogeneous data on uvby photometry and proper motion, and placed within 80 pc from the Sun. Components of space velocities, eccentricities of galactic orbits, perigalactic and apogalactic distances, and maximal remotness from galactic plane are presented for 1787 stars. ...

The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

MODELLING OF SPECTRA OF GRB HOST GALAXIES A. Moskvitin, E.Sonbas The method of estimation of internal extinction, mass and age of host galaxies is demonstrated for three galaxies: GRB 980703, GRB 000210 and GRB 060218. The method of two-component modeling was applied: the theoretical spectrum is the sum of the spectrum of the burst component and the spectrum of the old stellar population which determines the galaxy age. ... In other galaxies the internal extinction turned out to be low. ...
