XMM - Newton X - ray Observations of the Wolf - Rayet Binary System WR 147
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 nitrogen-type WN8 star plus an OB companion whose winds are interacting to produce a colliding wind shock. X-ray spectra from the pn and MOS detectors confirm the high extinction reported from IR studies and reveal ho...
متن کاملThe colliding - wind binary WR 140 : the particle acceleration laboratory
WR+O star binary systems exhibit synchrotron emission arising from relativistic electrons accelerated where the wind of the WR star and that of its massive binary companion collide-the wind-collision region (WCR). These " colliding-wind " binaries (CWB), provide an excellent laboratory for the study of particle acceleration, with the same physical processes as observed in SNRs, but at much high...
متن کاملSpectroscopic observations of the interacting binary BYCrucis
We present multi-wavelength spectroscopic data of the 106 day period interacting binary BY Crucis (Daems et al. 1997). The system consist of an early F-type supergiant that fills its Roche lobe and a more massive companion, hidden in a thick accretion disc. In the far-UV spectra (from 1200 Å to 1950 Å), strong emission lines of highly ionised elements are observed, superposed on a continuum. Bo...
متن کاملColliding Stellar Wind Models with Nonequilibrium Ionization: X-rays from WR 147
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 model is used to analyze the most recent X-ray spectra of the WR+OB binary system WR 147 . The basic result is that it can adequately reproduce the observed X-ray emission (spectral shape, observed flux) but some adjustm...
متن کاملStellar wind bubbles around WR and [WR] stars
We study the dynamics of stellar wind bubbles around hydrogen-deficient stars using numerical simulations with timeand ion dependent cooling. We consider two types of hydrogen-deficient stars, massive WR stars, producing Ring Nebulae, and low mass [WR] stars, producing Planetary Nebulae. We show that for the Planetary Nebulae, the different cooling properties of the hydrogen-deficient wind lead...
