Wolf-Rayet stars and black holes: mass distributions and evolutionary connection
I. A. Shaposhnikov, K. A. Postnov, A. M. Cherepashchuk
The form and relationship between the mass distributions of Wolf-Rayet stars and black holes are analyzed using a direct method for estimating the distribution function from a samp…
Near-IR and X-ray Variability of Cyg X-3: Evidence for a Compact IR Source and Complex Wind Structures
Igor I. Antokhin, Anatol M. Cherepashchuk, Eleonora A. Antokhina +1
We study near-infrared (JHK) and X-ray light curves of Cyg X-3 obtained with the 2.5-m telescope of the Caucasian Mountain Observatory of MSU SAI and collected from RXTE ASM and MA…
First tidal disruption events discovered by SRG/eROSITA: X-ray/optical properties and X-ray luminosity function at z<0.6
S. Sazonov, M. Gilfanov, P. Medvedev +22
We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-sky survey. These 13 events were selected among X-ray transients detected in the 0<l<180…
Compact nuclear objects and properties of their parent galaxies
Anatoly Zasov, Anatoly Cherepashchuk
We consider the relationship between the masses of the compact nuclear objects in the centers of disky galaxies -- supermassive black holes (SMBHs) or nuclear star clusters (NCs) -…
MN112: a new Galactic candidate Luminous Blue Variable
V. V. Gvaramadze, A. Y. Kniazev, S. Fabrika +4
We report the discovery of a new Galactic candidate Luminous Blue Variable (cLBV) via detection of an infrared circular nebula and follow-up spectroscopy of its central star. The n…
Discovery of a new Wolf-Rayet star and its ring nebula in Cygnus
V. V. Gvaramadze, S. Fabrika, W. -R. Hamann +6
We report the serendipitous discovery of a ring nebula around a candidate Wolf-Rayet (WR) star, HBHA 4202-22, in Cygnus using the Spitzer Space Telescope archival data. Our spectro…
