... From the observed direction of interplanetary magnetic field lines, we believe this field comes from the Sun, carried by magnetic field lines dragged out by the solar wind . ... That is why magnetic field-line loops tend to keep back the solar wind, unlike the outward-bound lines in the "coronal holes" between them. ... The magnetic field at all these points is already so weak that the solar wind overpowers it and shifts its field lines, while its own motion--radially outward--remains unchanged. ...

... From the peculiar shape of the light curve in the visible spectral region (a long phase interval of light constancy was observed by Hensberge et al. in 1981 ), HD 56022 had been expected to show unambiguously the nonequatorial symmetry of its surface brightness distribution. However, analysis of the light curve has yielded a possible equatorial position of a spot. ... A solution seems only possible, if the light constancy over the long phase interval in the visible is not observed in the UV. ...

... We compare our results with the GRANAT X-ray observations of the Galactic center (Churazov et al. ... It is instructive to compare our results for the Galactic center starburst with what might be expected for a continuous star formation, with the average rate characteristic for the whole Galaxy. For this continuous star formation model, we would expect to observe in the region of around the Galactic center about 10% of the total number of X-ray sources in the Galaxy. ...
