Orbital Parameters of the Unusual WR + O Binary System LS III +44 21
I. I. Antokhin, I. A. Shaposhnikov
We present the results of a spectroscopic study of the recently discovered WR + O binary system LS III +44 21. The system is unusual because, despite having characteristics similar…
The jet and circumstellar environment of the young binary DF Tau
A. V. Dodin, M. A. Burlak, V. A. Kiryukhina +5
Jets and disc winds play an important role in the evolution of protoplanetary discs and the formation of planetary systems. However, there is still a lack of observational data reg…
Spectroscopic Searches for Evolutionary Orbital Period Changes in WR+OB Binaries: the Case of WR 127 (Hen 3-1772)
I. A. Shaposhnikov, A. M. Cherepashchuk, A. V. Dodin +1
We aim at searching for secular evolution of the orbital period in the short-period binary system WR 127 (WN3b+O9.5V, ). We performed new low-resolution spectroscopic…
Spectroscopic Searches for Evolutionary Orbital Period Changes in WR+OB Binaries: the case of V444 Cyg
I. Shaposhnikov, A. Cherepashchuk, A. Dodin +1
We present the results of new photometric and spectroscopic observations of WN5+O6 binary V444 Cyg and a detailed analysis of extant spectroscopy and photometry. Using elements of…
Spectroscopic Searches for Evolutionary Orbital Period Changes in WR+OB Binaries: The case of CQ Cep and CX Cep
I. Shaposhnikov, A. Cherepashchuk, A. Dodin +1
We present the results of spectroscopic observations of two eclipsing WR+OB-type systems - CQ Cep and CX Cep, performed in 2020-2023 with a low-resolution slit spectrograph TDS ($λ…
Spectroscopic Variability of the Compact Planetary Nebula Hb 12
N. P. Ikonnikova, I. A. Shaposhnikov, V. F. Esipov +5
We present the results of our new low-resolution spectroscopic observations of the young compact planetary nebula Hb 12 performed in 2011-2020 with SAI MSU telescopes. We have meas…
