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…
A new paradigm for the X-ray emission of O stars from XMM-Newton observations of the O9.7 supergiant zeta Orionis
A. M. T. Pollock
XMM-Newton observations of the O supergiant zeta Orionis (O9.7 Ib) extend knowledge of its high-resolution spectrum beyond the CVI line at 33.7 Angstroms and suggest a new framewor…
A search for Warm-Hot Intergalactic Medium features in the X-ray spectra of Mkn 421 with the XMM-Newton RGS
M. Ravasio, G. Tagliaferri, A. M. T. Pollock +2
We present the high-resolution X-ray spectra of Mkn 421 obtained in November 2003 with the RGS aboard the XMM-Newton satellite. This Target of Opportunity observation was triggered…
Quasi-simultaneous XMM-Newton and VLA observation of the non-thermal radio emitter HD\168112 (O5.5III(f^+))
M. De Becker, G. Rauw, R. Blomme +8
We report the results of a multiwavelength study of the non-thermal radio emitter HD168112 (O5.5III(f^+)). The detailed analysis of two quasi-simultaneous XMM-Newton and VLA observ…
The Conspicuous Absence of X-ray Emission from Carbon-Enriched Wolf-Rayet Stars
L. M. Oskinova, R. Ignace, W. -R. Hamann +2
The carbon-rich WC5 star WR 114 was not detected during a 15.9 ksec XMM-Newton observation, implying an upper limit to the X-ray luminosity of Lx < 2.5*10^{30} erg/s and to the X-r…
High-Resolution X-ray Imaging of the Colliding Wind Shock in WR147
J. M. Pittard, I. R. Stevens, P. M. Williams +4
We analyze new high-resolution Chandra X-ray images of the Wolf-Rayet binary system WR147. This system contains a WN8 star with an early-type companion located 0.6'' to its north,…
