A giant exoplanet orbiting a very low-mass star challenges planet formation models
J. C. Morales, A. J. Mustill, I. Ribas +179
Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…
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…
Is there a compact companion orbiting the late O-type binary star HD 164816?
L. Trepl, V. V. Hambaryan, T. Pribulla +7
We present a multi-wavelength (X-ray, -ray, optical and radio) study of HD 194816, a late O-type X-ray detected spectroscopic binary. X-ray spectra are analyzed and the X-ray ph…
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…
