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-…
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…
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…
