Spectral atlas of two peculiar supergiants: MWC314 and IRC+10420
E. L. Chentsov, V. G. Klochkova, N. S. Tavolganskaya
An atlas of spectra of the unique high luminosity objects MWC 314 and IRC+10420 taken with the CCD echelle spectrograph (R=15000) at the prime focus of the 6-m telescope of SAO is…
High Resolution Optical Spectroscopy of the F Supergiant Proto-Planetary Nebula V887 Her=IRAS 18095+2704
Timur Sahin, David L. Lambert, Valentina G. Klochkova +1
An abundance analysis is presented for IRAS 18095+2704 (V887 Her), a post-AGB star and proto-planetary nebula. The analysis is based on high-resolution optical spectra from the McD…
New Spectroscopic Observations of the Post-AGB Star V354Lac=IRAS22272+5435
V. G. Klochkova, V. E. Panchuk, N. S. Tavolganskaya
The strongest absorption features with the lower-level excitation potentials eV are found to be split in the high-resolution optical spectra of the post-AGB star V3…
Optical spectrum of the post-AGB star HD56126 in the region 4010-8790 AA
V. G. Klochkova, E. L. Chentsov, N. S. Tavolganskaya +1
We studied in detail the optical spectrum of the post-AGB star HD56126 (IRAS07134+1005). We use high resolution spectra (R=25000 and 60000) obtained with the echelle spectrographs…
IR-source IRAS20508+2011: spectral variability of the central star
V. G. Klochkova, V. E. Panchuk, N. S. Tavolganskaya +2
Over the five years of high-resolution spectroscopy of the cool star identified with the IR source IRAS20508+2011, the photospheric radial velocity variability Vr=15-30km/s is dete…
