Spectroscopic and photometric variability of the O9.5Vp star HD93521
G. Rauw, M. De Becker, H. van Winckel +7
The line profile variability and photometric variability of the O9.5 Vp star HD93521 are examined in order to establish the properties of the non-radial pulsations in this star. Fo…
Close-up of primary and secondary asteroseismic CoRoT targets and the ground-based follow-up observations
K. Uytterhoeven, E. Poretti, M. Rainer +13
To optimise the science results of the asteroseismic part of the CoRoT satellite mission a complementary simultaneous ground-based observational campaign is organised for selected…
Oscillating Blue Stragglers, gamma Doradus stars and eclipsing binaries in the open cluster NGC2506
T. Arentoft, J. De Ridder, F. Grundahl +9
This is the first step in a project to combine studies of eclipsing binaries and oscillating stars to probe the interior of Blue Stragglers (BS). This may imply a way to discrimina…
Statistical properties of a sample of periodically variable B-type supergiants - Evidence for opacity-driven gravity-mode oscillations
K. Lefever, J. Puls, C. Aerts
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 go…
A Grid of FASTWIND NLTE Model Atmospheres of Massive Stars
K. Lefever, J. Puls, C. Aerts
In the last few years our knowledge of the physics of massive stars has improved tremendously. However, further investigations are still needed, especially regarding accurate calib…
High-precision elements of double-lined spectroscopic binaries from combined interferometry and spectroscopy. Application to the beta Cephei star beta Centauri
M. Ausseloos, C. Aerts, K. Lefever +2
We present methodology to derive high-precision estimates of the fundamental parameters of double-lined spectroscopic binaries. We apply the methods to the case study of the double…
X-RED: A Satellite Mission Concept To Detect Early Universe Gamma Ray Bursts
Mirko Krumpe, Deirdre Coffey, Georg Egger +14
Gamma ray bursts (GRBs) are the most energetic eruptions known in the Universe. Instruments such as Compton-GRO/BATSE and the GRB monitor on BeppoSAX have detected more than 2700 G…
An asteroseismic study of the Beta Cephei star Theta Ophiuchi: spectroscopic results
M. Briquet, K. Lefever, K. Uytterhoeven +1
We present the results of a detailed analysis of 121 ground-based high-resolution high S/N spectroscopic measurements spread over 3 years for the Beta Cephei star Theta Ophiuchi. W…
