Long-term high-resolution spectroscopic monitoring of the evolved metal-poor binary PS Gem
V. G. Klochkova, V. E. Panchuk, J. K. Zhao +3
We present results of long-term high-resolution spectroscopic monitoring of the extremely low-metallicity star PS Gem (=HD 52961), associated with IRAS 07008+1050. The spectra were…
B[e]-star CI Cam: a high-resolution spectrum atlas in the range of 395780 nm
Valentina G. Klochkova, Anatoly S. Miroshnichenko, Victoria N. Komarova +1
The atlas of the spectrum of the B[e] star CI Cam obtained with the 6-meter BTA telescope in combination with the NES spectrograph in the wavelength interval of 395780 nm with a…
Instabilities of the kinematic state of the atmospheres of some single C-rich post-AGB stars
Valentina G. Klochkova, Vladimir E. Panchuk, Nonna S. Tavolzhanskaya +1
To search for and study the instabilities in the atmospheres of selected post-AGB stars, we have performed a long-term high-resolution spectroscopy (R=60000) with the spectrograph…
High resolution optical spectra of the dormant LBV star P Cyg
Valentina G. Klochkova, Vladimir E. Panchuk, Nonna S. Tavolzhanskaya
High resolution optical spectra (R = 60 000) of the LBV star P Cyg beyond outburst were obtained on the 6-meter BTA telescope in the wavelength range 477-780 nm. We perform a detai…
Instability in the system of the distant post-AGB star LS III+52 24 (IRAS 22023+5249)
V. G. Klochkova, A. S. Miroshnichenko, V. E. Panchuk +2
The optical spectra of the B-supergiant LS III+52 24 (IRAS 22023+5249) obtained at the 6-meter telescope BTA with a resolution R60000 in 2010-2021 revealed signs of wind varia…
High-resolution optical spectroscopy of the post-AGB supergiant V340 Ser (=IRAS 172791119)
V. G. Klochkova, V. E. Panchuk, N. S. Tavolzhanskaya +1
Some evidences of wind variability and velocity stratification in the extended atmosphere has been found in the spectra of the supergiant V340 Ser (=IRAS 172791119) taken at the…
