Differential Luminosity Response of Balmer-Line Profiles in Galactic B/A Luminous Stars
N. L. Vaidman, S. A. Khokhlov, Sh. T. Nurmakhametova +3
We investigate the differential luminosity response of the optical Balmer series from H8 to H-alpha in Galactic B5-A5 luminous stars using homogeneous measurements of central depth…
An Empirical Effective-Temperature Calibrations for Galactic B/A Supergiants
N. L. Vaidman, A. S. Miroshnichenko, Sh. T. Nurmakhametova +9
We present empirical effective temperature Teff calibrations for Galactic supergiants of spectral types B5-A5 based on optical spectra. The relationships were derived from a refere…
Dynamical Masses and Radiative Transfer Modeling of HD 698: a Be Binary in Evolutionary Transition
Ilfa A. Gabitova, Alex C. Carciofi, Tajan H. de Amorim +13
We present a detailed analysis of the early post-mass-transfer binary HD 698 (V742 Cas) combining high-resolution optical spectroscopy, long-baseline interferometry, and radiative-…
The B[e] Phenomenon in Supergiants. A Result of Mass Transfer in Binaries, Mergers, or What?
Anatoly S. Miroshnichenko, Sergey V. Zharikov, Nadezhda L. Vaidman +1
The B[e] phenomenon discovered nearly 50 years ago features the presence of forbidden emission lines due to extended and dense circumstellar gas and large IR excesses due to the ra…
Hot donors in cataclysmic variables: The case of EI Psc
J. Kára, S. Zharikov, M. Wolf +4
Context: We present results of time-resolved optical spectroscopy and photometry of the short-orbital period dwarf nova EI Psc. Aims: This study aims to determine fundamental syste…
The Z Camelopardalis-type star AY Piscium: stellar and accretion disk parameters
Jan Kára, Sergey Zharikov, Marek Wolf +5
We present a new study of the Z~Cam-type eclipsing cataclysmic variable AY~Piscium with the aim of determining the fundamental parameters of the system and the structure of the acc…
Structure of accretion flows in the nova-like cataclysmic variable RW Tri
G. Subebekova, S. Zharikov, G. Tovmassian +5
We obtained photometric observations of the nova-like cataclysmic variable RW Tri and gathered all available AAVSO and other data from the literature. We determined the system para…
Properties of Galactic B[e] Supergiants: V. 3 Pup -- constraining the orbital parameters and modeling the circumstellar environments
A. S. Miroshnichenko, S. Danford, S. V. Zharikov +9
We report the results of a long-term spectroscopic monitoring of the A-type supergiant with the B[e] phenomenon 3 Pup = HD 62623. We confirm earlier findings that it is a binary sy…
IRAS 22150+6109 - a young B-type star with a large disc
Olga V. Zakhozhay, Anatoly S. Miroshnichenko, Kenesken S. Kuratov +4
We present the results of a spectroscopic analysis and spectral energy distribution (SED) modelling of the optical counterpart of the infrared source IRAS 22150+6109. The source wa…
Toward Understanding the B[e] Phenomenon. VII. AS 386, a single-lined binary with a candidate black hole component
S. A. Khokhlov, A. S. Miroshnichenko, S. V. Zharikov +24
We report the results of spectroscopic and photometric observations of the emission-line object AS 386. For the first time, we found that it exhibits the B[e] phenomenon and fits t…
Nonlinear fractal meaning of the Hubble constant
Zeinulla Zhanabaev, Serik Khokhlov, Aldiyar Agishev
According to astrophysical observations value of recession velocity in a certain point is proportional to a distance to this point. The proportionality coefficient is the Hubble co…

We report the results of high-resolution () spectroscopic observations of the emission-line object HD 85567, which has been classified as a FS CMa type object or a p…
Informational and entropic criteria of self-organization
Zeinulla Zh. Zhanabaev, Yeldos T. Kozhagulov, Serik A. Khokhlov
The work is devoted to study of the following problem: can we use any qualitative criteria for realization of such universal phenomenon as self-organization in open systems? We hav…
