An X-ray and Optical Study of the Dwarf Nova Candidate OGLE-BLG-DN-0064
A. B. Sibgatullin, V. I. Dodon, I. I. Galiullin +3
The source OGLE-BLG-DN-0064 (hereafter OGLE64) was classified as a potential dwarf nova based on its regular outburst activity revealed by the OGLE optical survey. In this paper, w…
Spectroscopy of globular clusters in the dwarf spheroidal galaxy IKN
M. E. Sharina, V. V. Shimansky
Moderate resolution spectra of four globular clusters in the dwarf spheroidal galaxy IKN obtained with the 6-m telescope of the Special Astrophysical Observatory have been used to…
Horizontal branch structure, age, and chemical composition for very metal-poor extragalactic globular clusters
M. E. Sharina, M. I. Maricheva, A. Y. Kniazev +2
This paper presents the results of analysing the integrated light (IL) low-resolution spectra of globular clusters (GCs) in the M31 and Centaurus A groups of galaxies. The sample c…
On accretion in the eclipsing polar BS Tri
A. I. Kolbin, N. V. Borisov, N. A. Serebriakova +4
We analyze spectroscopic and photometric observations of the eclipsing polar BS Tri. The polar's light curve shape variations can be interpreted by changing contributions of the ac…
SRGe2149+6736 -- the new candidate to AM~Her type variables discovered by eROSITA telescope on "Spectrum--Roentgen--Gamma" orbital observatory
I. F. Bikmaev, A. I. Kolbin, V. V. Shimansky +18
We present the results of the optical identification, classification, as well as analysis of photometric and spectral observations of the X-ray transient SRGe2149+6736 detected by…
On the influence of multiple stellar populations in globular clusters on their medium-resolution integrated-light spectra
M. E. Sharina, V. V. Shimansky
We take a closer look at our published results of determination of ages, metallicities, helium mass fractions and abundances of chemical elements in Galactic globular clusters in o…
