X-Ray Spectroscopy of Stars
M. Guedel, Y. Naze
(abridged) Non-degenerate stars of essentially all spectral classes are soft X-ray sources. Low-mass stars on the cooler part of the main sequence and their pre-main sequence prede…
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…
The massive binary HD 152218 revisited: A new colliding wind system in NGC 6231
H. Sana, Y. Nazé, B. O'Donnell +2
We present the results of an optical and X-ray monitoring campaign on the short-period massive SB2 binary HD 152218. Combining our HiRes spectroscopic data with previous observatio…
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…
