In this paper, we present the results of a study of the variability of the prototype polar AM Her using one of the complementary mathematical methods. Results of modeling of the auto-correlation analysis of a 24117 second long Chandra observation are

Based on the Gaia EDR3 astrometric parameters and our new systemic radial velocity of the high-mass X-ray binary 4U 2206+54/BD+53 2790, we studied the trace back motion of the system and propose that it originated in the subgroup of the Cepheus OB1 a

The ROSAT source 1RXS J181333.7+453118 is a Seyfert Sy1 galaxy with a red shift of z=0.093. A ROSAT spectrum and a spectrum over wavelengths of λ4500-7250A taken with the 2.6-m telescope at the Byurakan Astrophysical Observatory are shown. The x-ray

We present new observations of seven late-type stars previously discovered in the First Byurakan Survey (FBS). These observations prove that they belong to the family of carbon (C) stars. Seventy-nine similar FBS C stars were previously known. The se

The properties of OH megamaser galaxies in the x-ray region are discussed. Observational data from the XMM-Newton x-ray satellite are presented for three megamasers, IRAS 01418+1651, IRAS 11010+4107, and IRAS 13218+0552. Based on a sample of OH megam

A 6 hour patrol search in the region of the Pleiades aggregate with the 40″ and 21″ Schmidt telescopes at the Byurakan Astrophysical Observatory provided simultaneous data in two colors (Pg and U) on a flare of the star FSP 377=HII 2411 in the Hy

We present an analysis of the X-ray light curves of the magnetic cataclysmic variable DP Leo using recently performed XMM-Newton EPIC and archival ROSAT PSPC observations. We determine the eclipse length at X-ray wavelengths to be 235 +-5 s, slightly

Trapezium type multiple stars are centers of star formation in stellar associations. Theoretical and observational studies show that they are dynamically instable. Due to the special space configurations of the components, Trapezium type multiple sta

The X-ray data of a sample of 104 flare stars (FSs) in the Pleiades cluster region obtained by Stauffer et al. [1] on the basis of deep ROSAT PSPC observations are analyzed. If we divide the X-ray emission detected in late-type stars of the Pleiades
