Optical spectroscopy of the Be/black hole binary MWC656 -- interaction of a black hole with a circumstellar disc
R. K. Zamanov, K. A. Stoyanov, D. Marchev +7
We present new spectroscopic observations of the Be/black hole binary MWC 656 obtained during the period 2015 - 2021. We measure the equivalent width of H (EW), H (…

Radius, rotational period and inclination of the Be stars in the Be/gamma-ray binaries MWC 148 and MWC 656
R. K. Zamanov, K. A. Stoyanov, J. Marti +2
Using TESS photometry and Rozhen spectra of the Be/gamma-ray binaries MWC 148 and MWC 656, we estimate the projected rotational velocity (), the rotational period (P$_…

An eccentric wave in the circumstellar disc of the Be/X-ray binary X Persei
R. K. Zamanov, K. A. Stoyanov, U. Wolter +7
We present spectroscopic observations of the Be/X-ray binary X Per obtained during the period December 2017 - January 2020 (MJD~58095 - MJD~58865). In December 2017 the , ,…
