B stars seen at high resolution by XMM-Newton
Constantin Cazorla, Yael Naze
We report on the properties of 11 early B stars observed with gratings on board XMM-Newton and Chandra, thereby doubling the number of B stars analysed at high resolution. The spec…
Chemical abundances of fast-rotating massive stars. II. Interpretation and comparison with evolutionary models
Constantin Cazorla, Yaël Nazé, Thierry Morel +3
Aims: Past observations of fast-rotating massive stars exhibiting normal nitrogen abundances at their surface have raised questions about the rotational mixing paradigm. We revisit…
pi Aqr is another gamma-Cas object
Yael Naze, Gregor Rauw, Constantin Cazorla
The gamma-Cas category is a subgroup of Be stars displaying a strong, hard, and variable thermal X-ray emission. An XMM-Newton observation of pi Aqr reveals spectral and temporal c…
Chemical abundances of fast-rotating massive stars. I. Description of the methods and individual results
Constantin Cazorla, Thierry Morel, Yael Naze +4
Aims: Recent observations have challenged our understanding of rotational mixing in massive stars by revealing a population of fast-rotating objects with apparently normal surface…
Wind collisions in three massive stars of Cyg OB2
Constantin Cazorla, Yael Naze, Gregor Rauw
Aims: We wish to study the origin of the X-ray emission of three massive stars in the Cyg OB2 association: Cyg OB2 #5, #8A, #12. Methods: To this aim, dedicated X-ray observations…
