In accreting binary neutron star systems matter is channelled by the strong magnetic field to the poles of the neutron star. The accreted matter accumulates at the poles to form accretion mounds. Pressure from the confined matter can significantly distort the local magnetic field structure, affecting the X-ray observations and long term evolution of the magnetic field. ...

This process is thought to occur in circumstellar disks of gas and dust around young stars on rather short timescales : infrared surveys show that the number of low mass stars with disks drops dramatically for stars older than 10 Myr, suggesting that in order to form large solids before the disk disperses, the growth process has to take place within a few million years. ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
