The radial velocity curve for HeII emission cannot be used for component mass determination in SS433
A. V. Dodin, K. A. Postnov, A. M. Cherepashchuk
More than 150 measurements of the HeII 4686A emission line in spectra of SS433 were obtained during 388 nights in 2020-2025 with the Transient Double-beam Spectrograph on the 2.5 m…
The massive binary system WR 20a: light curve analysis in a colliding wind model
I. I. Antokhin, E. A. Antokhina, A. M. Cherepashchuk
The article presents the results of the analysis of optical light curves of the massive binary system WR 20a (WN 6ha + WN 6ha). The analysis was performed with the binary system mo…
Empirical correlation between masses of black holes and Wolf-Rayet stars derived from their mass distributions in spectroscopic binaries
Konstantin Postnov, Ivan Shaposhnikov, Anatol Cherepashchuk
We present observationally determined mass distributions of Wolf-Rayet (WR) stars in WR+OB binaries and black holes (BH) in spectroscopic binaries. Both WR and BH mass probability…
Transient narrow high-velocity absorptions in the stationary spectra of SS433
A. V. Dodin, K. A. Postnov, A. M. Cherepashchuk +1
We report on the discovery of rare emergence (31 nights from 360 nights of observations) of narrow absorption features in hydrogen and helium lines in stationary SS433 spectra with…
