A spectroscopic investigation of the O-type star population in four Cygnus OB associations. II. Determination of the fundamental parameters
L. Mahy, G. Rauw, M. De Becker +2
Aims. Having established the binary status of nineteen O-type stars located in four Cygnus OB associations, we now determine their fundamental parameters to constrain their propert…
Phase resolved X-ray spectroscopy of HDE228766: Probing the wind of an extreme Of+/WNLha star
G. Rauw, L. Mahy, Y. Naze +3
HDE228766 is a very massive binary system hosting a secondary component, which is probably in an intermediate evolutionary stage between an Of supergiant and an WN star. The wind o…
Epoch-dependent absorption line profile variability in lambda Cep
J. M. Uuh-Sonda, G. Rauw, P. Eenens +4
We present the analysis of a multi-epoch spectroscopic monitoring campaign of the O6Ief star lambda Cep. Previous observations reported the existence of two modes of non-radial pul…
A spectroscopic investigation of the O-type star population in four Cygnus OB associations. I. Determination of the binary fraction
L. Mahy, G. Rauw, M. De Becker +2
Context. Establishing the multiplicity of O-type stars is the first step towards accurately determining their stellar parameters. Moreover, the distribution of the orbital paramete…
A detailed X-ray investigation of zeta Puppis I. The dataset and some preliminary results
Yael Naze, Carlos Arturo Flores, Gregor Rauw
Aims: zeta Puppis, one of the closest and brightest massive stars, was the first early-type object observed by the current generation of X-ray observatories. These data provided so…
