HD148937: a multiwavelength study of the third Galactic member of the Of?p class

Y. Naze, N. R. Walborn, G. Rauw +3

Three Galactic O-type stars belong to the rare class of Of?p objects: HD108, HD191612, and HD148937. The first two stars show a wealth of phenomena, including magnetic fields and s…

Chandra monitoring of the very massive binary WR20a and the young massive cluster Westerlund2

Yael Naze, Gregor Rauw, Jean Manfroid

Results: The two Wolf-Rayet stars WR20a (WN6ha+WN6ha) and WR20b (WN6ha) were analyzed in detail. They are both very luminous and display very hard spectra, but WR20b does not seem…

First detection of phase-dependent colliding wind X-ray emission outside the Milky Way

Yael Naze, Michael F. Corcoran, Gloria Koenisgberger +1

After having reported the detection of X-rays emitted by the peculiar system HD5980, we assess here the origin of this high-energy emission from additional X-ray observations obtai…

Towards an understanding of the Of?p star HD191612: Phase-resolved multiwavelength observations

Yael Naze, Gregor Rauw, A. M. T. Pollock +2

We present the analysis of phase-resolved X-ray and optical observations of the peculiar hot star HD191612 (Of?p). This star is known to display line-profile variations that are re…

An XMM-Newton view of the young open cluster NGC 6231 -- II. The OB star population

H. Sana, G. Rauw, Y. Naze +2

In this second paper, we pursue the analysis of the 180 ks XMM-Newton campaign towards the young open cluster NGC 6231 and we focus on its rich OB star population. We present a lit…
