A quantitative study of O stars in NGC2244 and the Mon OB2 association
F. Martins, L. Mahy, G. Rauw +1
Our goal is to determine the stellar and wind properties of seven O stars in the cluster NGC2244 and three O stars in the OB association MonOB2. These properties give us insight in…
CoRoT observations of O stars: diverse origins of variability
R. Blomme, M. Briquet, P. Degroote +26
Six O-type stars were observed continuously by the CoRoT satellite during a 34.3-day run. The unprecedented quality of the data allows us to detect even low-amplitude stellar pulsa…
Variability in the CoRoT photometry of three hot O-type stars. HD 46223, HD 46150 and HD 46966
R. Blomme, L. Mahy, C. Catala +15
The detection of pulsational frequencies in stellar photometry is required as input for asteroseismological modelling. The second short run (SRa02) of the CoRoT mission has provide…
The two components of the evolved massive binary LZ Cep. Testing the effects of binarity on stellar evolution
L. Mahy, F. Martins, C. Machado +2
Aims. We present an in-depth study of the two components of the binary system LZCep in order to constrain the effects of binarity on the evolution of massive stars. Methods. We use…
