Long-term high-resolution spectroscopic monitoring of the evolved metal-poor binary PS Gem
V. G. Klochkova, V. E. Panchuk, J. K. Zhao +3
The paper reports three decades of high‑resolution spectroscopic observations of the metal‑poor binary star PS Gem, analyzing Hα line variations and radial velocities to characteri…
Detection of pulsations and a non-stable wind in IRAS 01005+7910, an object with the B[e]-phenomenon
Anatoly S. Miroshnichenko, Valentina G. Klochkova, Vladimir E. Panchuk +1
Comparison of the spectra obtained at different observing dates shows significant variations in the complex H and H line profiles, such as a systematic increase in their em…
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…
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…
