We present spectroscopic evidence that the luminosity of HD 183143 is higher by one magnitude than thought previously. The star is yet another B6-8 Ia-0 white hypergiant of the Galaxy. Its absolute visual magnitude is close to −8m, and its distance is close to 2 kpc. We describe spectroscopic manifestations of the nonstationary behavior of its atmosphere and wind. 
Spectroscopy of 13 high-mass stars in the Cyg OB2 association
The NES echelle spectrograph of the 6-m telescope of the Special Astrophysical Observatory has been used to obtain high-resolution spectra for 13 hot O3-B4 stars in the Cyg OB2 association, making it
Echelle spectra of HD 183143 [B7Iae, E(B − V) = 1.27] were obtained on three nights, at a resolving power R = 38,000 and with a signal-to-noise ratio ≈ 1000 at 6400 Å in the final, combined spectrum.
High-resolution optical spectroscopy of the yellow hypergiant V1302 Aql (=IRC+10420) in 2001–2014
We present the results of a study of spectral features and the velocity field in the atmosphere and circumstellar envelope of the yellow hypergiant V1302 Aql, the optical counterpart of the IR source
Doppler splitting in diffuse interstellar bands
We demonstrate evident Doppler splitting in the profiles of many narrow diffuse interstellar bands (DIBs). Their components are compared with those of atomic and molecular lines of interstellar
The Apache Point Observatory Catalog of Optical Diffuse Interstellar Bands
Aiming for a new and more comprehensive DIB catalog between 4000 and 9000 Å, we revisited the Atlas Catalog based on the observations of HD 183143 and HD 204827. Twenty-five medium to highly reddened
C60+ – looking for the bucky-ball in interstellar space
The laboratory gas phase spectrum recently published by Campbell et al. has reinvigorated attempts to confirm the presence of the C$_{60}^+$ cation in the interstellar medium, thorough an analysis of
Validation of the new Hipparcos reduction
Context. A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming accuracies for nearly all stars brighter than magnitude Hp = 8 to be better, by up

An atlas of spectra of B6–A2 hypergiants and supergiants from 4800 to 6700 Å
We present an atlas of spectra of 5 emission-line stars: the low-luminosity luminous blue variables (LBVs) HD 168625 and HD 160529, the white hypergiants (and LBV candidates) HD 168607 and AS 314,
The diffuse interstellar bands. IX: Constraints on the identification
Equivalent widths of the diffuse interstellar bands (DIBs) λλ5780, 5797 and of the interstellar D1 and D2 lines have been measured on Lick and Canada-France-Hawaii Telescope coude spectrograms of 93
Narrow Diffuse Interstellar Bands: A Survey with Precise Wavelengths
We present an atlas of 271 diffuse interstellar bands (DIBs) between 4460 and 8800 Å based on echelle spectra (R = 45,000), of which more than 100 are new DIBs discovered in this survey. The atlas is
A survey of diffuse interstellar bands (3800-8680 A)
A systematic search for diffuse interstellar absorption bands in the spectra of four reddened early type stars has resulted in the detection of 64 new bands and another 69 possible interstellar
A deep echelle survey and new analysis of diffuse interstellar bands
We report a deep survey of diffuse interstellar bands (DIBs) between 3906 A and 6812 Aunder consistent observing conditions toward three very reddened and five unreddened stars. BD+63° 1964's
A [ITAL]Hipparcos[/ITAL] Census of the Nearby OB Associations
A comprehensive census of the stellar content of the OB associations within 1 kpc from the Sun is presented, based on Hipparcos positions, proper motions, and parallaxes. It is a key part of a
The Diffuse Interstellar Bands
The diffuse interstellar bands are absorption features observed in the spectra of stars seen through significant column densities of interstellar material. Of the 127 confirmed DIBs in the optical
Studies of luminous stars in nearby galaxies. I. Supergiants and O stars in the Milky Way.
In this paper the fundamental properties of the brightest known stars in our Galaxy are determined for future comparison with results for the most luminous stars in other galaxies. The H-R diagrams
Fundamental stellar photometry for standards of spectral type on the revised system of the Yerkes spectral atlas
Photometry and spectroscopy are among the most important and fundamental types of astronomical observations. By the middle of the twentieth century most spectral classification was defined in terms
Long-term spectroscopic monitoring of the Luminous Blue Variable HD 160529
We have spectroscopically monitored the galactic Luminous Blue Variable HD160529 and obtained an extensive high-resolution data set that covers the years 1991 to 2002. During this period, the star
