Spectroscopic variability of two Oe stars
G. Rauw, T. Morel, Y. Naze +28
The Oe stars HD45314 and HD60848 have recently been found to exhibit very different X-ray properties: whilst HD60848 has an X-ray spectrum and emission level typical of most OB sta…
The variable stellar wind of Rigel probed at high spatial and spectral resolution
O. Chesneau, A. Kaufer, O. Stahl +5
We present a spatially resolved, high-spectral resolution (R=12000) K-band temporal monitoring of Rigel using AMBER at the VLTI. Rigel was observed in the Bracket Gamma line and it…
Broad-band Spectroscopy of the Ongoing Large Eruption of the Luminous Blue Variable R71
A. Mehner, D. Baade, T. Rivinius +4
The Luminous Blue Variable (LBV) R71 is currently undergoing an eruption, which differs photometrically and spectroscopically from its last outburst in the 1970s. Valuable informat…
The WR 140 periastron passage 2009: first results from MONS and other optical sources
R. Fahed, A. F. J. Moffat, J. Zorec +29
We present the results from the spectroscopic follow-up of WR140 (WC7 + O4-5) during its last periastron passage in January 2009. This object is known as the archetype of colliding…
High spatial resolution monitoring of the activity of BA supergiant winds
Olivier Chesneau, Luc Dessart, A. Kaufer +4
There are currently two optical interferometry recombiners that can provide spectral resolutions better than 10000, AMBER/VLTI operating in the H-K bands, and VEGA/CHARA, recently…
Variability monitoring of OB stars during the Mons campaign
T. Morel, G. Rauw, T. Eversberg +28
We present preliminary results of a 3-month campaign carried out in the framework of the Mons project, where time-resolved Halpha observations are used to study the wind and circum…
