Using optical spectroscopy a nature of ultraluminous X-ray sources in external galaxies whose X-ray luminosities exceed the luminosities of the brightest black holes in our Galaxy by thousands of times was revealed. More...

The sample of the Local Volume galaxies (distance smaller than 10 Mpc) gives a unique opportunity to study the properties of galaxies including the weakest objects: the absolute magnitude MB≈-10 and the virial mass Mvir≈109M☼. More...

Based on the magnetic field measurements of the chemically peculiar star HD965, conducted in 2000-2015 with the SAO RAS 6-m telescope, we have found that this object is an ultra slow magnetic rotator with a rotation period of about 20 years. The obtained result is strong evidence in favor of the so-called fossil theory of large-scale field formation in these objects. More...
