  journal={Astronomy and Astrophysics},
Aims. We provide a quantitative analysis of time-variable phenomena in the photospheric, near-star, and outflow regions of the late-B supergiant (SG) HD 199 478. This study aims to provide new perspectives on the nature of outflows in late-B SGs and on the influence of large-scale structures rooted at the stellar surface. Methods. The analysis is based primarily on optical spectroscopic datasets secured between 1999 and 2000 from the Bulgarian NAO, Tartu, and Ritter Observatories. The acquired…

Wind properties of variable B supergiants
Context. Variable B supergiants (BSGs) constitute a heterogeneous group of stars with complex photometric and spectroscopic behaviours. They exhibit mass-loss variations and experience different
Detection of a 1.59 h period in the B supergiant star HD 202850
Context. Photospheric lines of B-type supergiants show variability in their profile shapes. In addition, their widths are much wider than can be accounted for purely by stellar rotation. This excess
Low-frequency photospheric and wind variability in the early-B supergiant HD 2905
Despite the important advances in space asteroseismology during the last decade, the early phases of evolution of stars with masses above $\sim$15 M$_{\odot}$ have been only vaguely explored up to
The variable stellar wind of Rigel probed at high spatial and spectral resolution
Context. Luminous BA-type supergiants are the brightest stars in the visible that can be observed in distant galaxies and are potentially accurate distance indicators. The impact of the variability
Time, spatial, and spectral resolution of the Hα line-formation region of Deneb and Rigel with the VEGA/CHARA interferometer
BA-type supergiants are amongst the most optically-bright stars. They are observable in extragalactic environments, hence potential accurate distance indicators. Emission activity in the Halpha line
The Galactic unclassified B[e] star HD 50138 - III. The short-term line profile variability of its photospheric lines
Context. HD 50138 presents the B[e] phenomenon, but its nature is not clear yet. This star is known to present spectral variations, which have been associated with outbursts and shell phases. Aims.
Observational evidence for a correlation between macroturbulent broadening and line-profile variations in OB supergiants
The spectra of O and B supergiants (Sgs) are known to be affected by a significant form of extra line broadening (usually referred to as macroturbulence) in addition to that produced by stellar
Interplay between pulsations and mass loss in the blue supergiant 55 Cygnus = HD 198 478
Blue supergiant stars are known to display photometric and spectroscopic variability that is suggested to be linked to stellar pulsations. Pulsational activity in massive stars strongly depends on
Delta-slow solution to explain B supergiant stars' winds
Abstract A new radiation-driven wind solution called δ-slow was found by Curé et al. (2011) and it predicts a mass-loss rate and terminal velocity slower than the fast solution (m-CAK, Pauldrach et
A Five-year Spectroscopic and Photometric Campaign on the Prototypical α Cygni Variable and A-type Supergiant Star Deneb
Deneb is often considered the prototypical A-type supergiant and is one of the visually most luminous stars in the Galaxy. A-type supergiants are potential extragalactic distance indicators, but the


Bright OB stars in the Galaxy II. Wind variability in O supergiants as traced by Hα
We investigate the line-profile variability (lpv) of Hα for a large sample of O-type supergiants (15 objects between O4 and O9.7), in an objective, statistically rigorous manner. We employed the
Bright OB stars in the Galaxy - IV. Stellar and wind parameters of early to late B supergiants
Context. B-type supergiants represent an important phase in the evolution of massive stars. Reliable estimates of their stellar and wind parameters, however, are scarce, especially at mid and late
Multi-periodic photospheric pulsations and connected wind structures in HD 64760
We report on the results of an extended optical spectroscopic monitoring campaign on the early-type B supergiant HD64760 (B0.5Ib) designed to probe the deep-seated origin of spatial wind structure in
Understanding B-type supergiants in the low metallicity environment of the SMC II
Despite a resurgence of effort over the last decade in the area of massive stars there is still ambiguity over their evolutionary path, contamination of their surface abundances and the behaviour of
Large-scale wind structures in OB-supergiants: a search for rotationally modulated Hα variability
We present the results of a long-term monitoring campaign of the Hline in a sample of bright OB-supergiants (O7.5-B9) that aims at detecting rotationally modulated changes potentially related to the
Quantitative studies of the optical and UV spectra of Galactic early B supergiants - I. Fundamental parameters
Aims. We undertake an optical and ultraviolet spectroscopic analysis of a sample of 20 Galactic B0-B5 supergiants of luminosity classes Ia, Ib, Iab, and II. Fundamental stellar parameters are
Time-Series Observations of O Stars. II. Optical Observations of zeta Ophiuchi
We present photopolarimetry and extensive high-resolution, high-signal-to-noise optical spectroscopy of the rapidly rotating late O-type star zeta Ophiuchi (HD 149757). The polarimetric data show no
Quantitative spectroscopy of ba-type supergiants
Luminous BA-type supergiants have enormous potential for modern astrophysics. They allow topics ranging from non-LTE physics and the evolution of massive stars to the chemical evolution of galaxies
The H-R diagram of the Large Magellanic Cloud and implications for stellar evolution
An H-R diagram for the Large Magellanic Cloud is produced using a sample of 1375 normal spectral class O through G supergiants. The definition of normal includes all O stars that fit into the
Bright OB stars in the Galaxy. III. Constraints on the radial stratification of the clumping factor
Context. Recent results strongly challenge the canonical picture of massive star winds: various evidence indicates that currently accepted mass-loss rates, u M, may need to be revised downwards, by
