XMM-Newton observations of Zeta Orionis (O9.7 Ib): A Collisional Ionization Equilibrium model
A. J. J. Raassen, K. A. van der Hucht, N. A. Miller +1
We present XMM-Newton observations of the O supergiant Zeta Orionis (O9.7 Ib). The spectra are rich in emission lines over a wide range of ionization stages. The RGS-spectra show f…
XMM-Newton X-ray study of early type stars in the Carina OB1 association
I. I. Antokhin, G. Rauw, J. -M. Vreux +2
X-ray properties of the stellar population in the Carina OB1 association are examined with special emphasis on early-type stars. Their spectral characteristics provide some clues t…
Are WC9 Wolf-Rayet stars in colliding-wind binaries?
P. M. Williams, K. A. van der Hucht, G. Rauw
We present results from a spectroscopic search for massive companions to dust-making Galactic WC9 stars as a step to testing the paradigm that dust formation in these systems requi…
Wind clumping and the wind-wind collision zone in the Wolf-Rayet binary gamma Velorum
H. Schild, M. Guedel, R. Mewe +7
We present XMM-Newton observations of gamma^2 Velorum (WR 11, WC8+O7.5III, P = 78.53 d), a nearby Wolf-Ray binary system, at its X-ray high and low states. At high state, emission…
