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 M_B≈-10 and the virial mass M_vir≈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...

The Galactic low-mass X-ray binary GS 2023+338 was discovered during the burst on May 22, 1989 with the Japanise satellite Ginga (aka Galaxy). The flux reached 17 crabs (this unit of flux measurement is an bright X-ray source, Crab Nebula) at 10-35 keV. More...
