Colliding Stellar Wind Models with Nonequilibrium Ionization: X-rays from WR 147
Svetozar A. Zhekov
The effects of nonequilibrium ionization are explicitly taken into account in a numerical model which describes colliding stellar winds (CSW) in massive binary sytems. This new mod…

X-Rays From Massive OB Stars: Thermal Emission From Radiative Shocks
Svetozar A. Zhekov, Francesco Palla
Chandra gratings spectra of a sample of 15 massive OB stars were analyzed under the basic assumption that the X-ray emission is produced in an ensemble of shocks formed in the wind…

XMM-Newton X-ray Observations of the Wolf-Rayet Binary System WR 147
S. L. Skinner, S. A. Zhekov, M. Guedel +1
We present results of a 20 ksec X-ray observation of the Wolf-Rayet (WR) binary system WR 147 obtained with XMM-Newton. Previous studies have shown that this system consists of a n…
