Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...

... Using the photometric data for about 1400 disk-population red giants, we investigate the metallicity variations in function of the spectral class (colour and of the luminosity. ... The metal-dificient giant population of the galactic disk os fund to lack stars which could be older than the open cluster NGC 188, i.e. 7x10 9 years. ... По фотометрическим данным, примерно для 1400 красных гигантов диска Галактики исследованы вариации металличности в зависимости от спектра (цвета) и светимости. ...

... Our scientific interest is an accuracy of asteroid CCD observations obtained by amateurs and professional astronomers all over in the World. ... These data help us to analyse an accuracy of real CCD positions in the MPC Database. ... Do you test your observations of the small Solar System bodies permanently before sending them to the International Minor Planets' Center? ... Do you know a real accuracy of your positional CCD-observations in comparison with the other observatories' one ? ...

... Today this year's largest group of sunspots will cross the Sun's central meridian. ... The next day, the number of spots in the group reached five, and the day after, on June 2nd, it was possible to count thirteen sunspots on solar disk, which had been clear prior to this. ... This year's two most powerful active areas, which passed across the solar disk at the beginning of May, 2009, are set to appear in the Sun's eastern sector in two days, on June 6th. ...

... In the course of the BURAN orbiter development, suborbital and orbital launches of BOR-4 and BOR-5 flight vehicles have been produced for aerodynamic analysis and working capacity of thermal protection structures verification. ... The flights of the SPIRAL prototype and BOR-4 and BOR-5 flying vehicles have allowed not only to speed up the BURAN orbiter development, but also to justify the choice of the aerodynamic scheme of the orbital stage of the advanced MAKS aerospace system. ... Buran Orbiter ....

The purpose of the space-physics lab exercises is to introduce the students to the methods of the measurements, to the modern conception of near-Earth space structure and the physical processes and phenomena occured in it. ... At present the reasearches and the teachers of the University and of other institutes participating in the project continue development of the the special space-physics lab exercises, and they are interested in your ideas concerning the future exercises. ...
