... Initial mass function and binary stars . ... The principal goal of this study is to show that the real shape of the initial mass function for low- and intermediate-mass stars differs from the observed one. In particular, comparison of radii of eclipsing binary components and single stars shows a noticeable difference for B0V-G0V components of eclipsing binaries and single stars of the corresponding spectral type. ...

... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

. Comment on J1130-1449 . There are two dominant components in our image. Comparison with the 15 GHz image of Kellermann et al.
