Spectroscopic Variability of Supergiant Star HD14134, B3Ia
Profile variations in the $$\hbox {H}\alpha $$Hα and $$\hbox {H}\beta $$Hβ lines in the spectra of the star HD14134 are investigated using observations carried out in 2013–2014 and 2016 with the 2-m
Spectral variability of the STAR 55 Cyg B3 Ia
We study the variability of the Hα and Hβ lines in the spectrum of 55 Cyg based on observations carried out in 2010 on the 2-m telescope of the Shamakhy Observatory of the Azerbaijan National Academy
Hα profile variations in the spectrum of the supergiant HD14134
Variations of the Hα line in the spectra of the star HD14134 are investigated using observations carried out in 2013–2014 and in 2016 with the 2-m telescope at Shamakhy Astrophysical Observatory. In
SPECTROSCOPIC VARIABILITY OF THE SUPERGIANTS HD21389 AND HD187982
It has been revealed that absorption in the line of H has complex structure in the spectrum of the star HD21389 depending on the activity phase of the atmosphere. The profile of the line has inverse
Investigation of atmosphere nonstationarity in the supergiant HD225094: Profile variations of Hα and Hβ lines in spectra of the star HD225094
Some information on the supergiant star HD225094 and unusual features observed in the spectra obtained in 2013 at the Shamakhy Astrophysical Observatory are presented. It is found that profiles of
Hα and Hβ profile variations in the spectra of the star 55 Cyg
Profile variations in the Hα and Hβ lines in the spectra of the star 55 Cyg are investigated from observations acquired in 2010 at the Cassegrain focus of the 2-m telescope at the Shamakhy
