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 of the stellar winds on the distance determination remains poorly understood. Aims. Our aim is to probe the inhomogeneous structures in the stellar wind using spectro-interferometric monitoring. Methods. We present a spatially resolved, high-spectral resolution (R = 12 000) K-band temporal monitoring… 
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
Photospheric variability of the late B supergiant HD 199478
We present the results of spectral studies of the photospheric lines of the late B supergiant HD 199478 (B8 Iae) in the visual range. The radial velocities of photospheric lines, as well as the

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
Interferometric and spectroscopic monitoring of emission lines: detection of CIRs in hot star winds
We present a theoretical study of hot star wind variability in the presence of hypothetical large scale wind structures. Contrary to previous investigations that have focused on P-Cygni profiles, we
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
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
Extended optical spectroscopic monitoring of wind structure in HD 152408
New perspectives are provided on signicant spatial structure and temporal variability in the near- star wind regions (i.e. < 3 R?) of the massive luminous star HD 152408 (classied as O8:Iafpe or
Wind structure of late B supergiants. I. Multi-line analyses of near-surface and wind structure in H
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
AMBER, the near-infrared spectro-interferometric three-telescope VLTI instrument
Context: Optical long-baseline interferometry is moving a crucial step forward with the advent of general-user scientific instruments that equip large aperture and hectometric baseline facilities,
Statistical properties of a sample of periodically variable B-type supergiants. Evidence for opacity
Aims: We have studied a sample of 28 periodically variable B-type supergiants selected from the HIPPARCOS mission and 12 comparison stars covering the whole B-type spectral range. Our goal is to test
Magnetic field measurements and wind-line variability of OB-type stars
Context. The first magnetic fields in O- and B-type stars that do not belong to the Bp-star class, have been discovered. The cyclic UV wind-line variability, which has been observed in a significant
VEGA: Visible spEctroGraph and polArimeter for the CHARA array: principle and performance
Context. Among optical stellar interferometers, the CHARA Array located at Mt Wilson in California offers the potential of very long baselines (up to 330 m) and the prospect of coupling multiple beam
