Colliding 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 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 کاملParticle Acceleration in the Colliding Winds Binary Wr 140
RESUMEN Favor de proporcionar un resumen en español. If you cannot provide a spanish abstract, the editors will do this. Massive WR+O star systems produce high-temperature, shock-heated plasma where the wind of the WR star and that of its binary companion collide-the wind-collision region (WCR). The WCR is a source of thermal (e.g. hard X-rays) and non-thermal (e.g. synchrotron) emission, the l...
متن کاملRadio , X - ray , and γ - ray Emission Models of the Colliding Winds Binary WR 140
We use hydrodynamical models of the wind-collision region (WCR) in the archetype colliding-wind system WR140 to determine the spatial and spectral distribution of the radio, X-ray and γ-ray emission from shock accelerated electrons. Our calculations are for orbital phase 0.837 when the observed radio emission is close to maximum. Using the observed thermal X-ray emission at this phase in conjun...
متن کاملHigh resolution radio studies of WR colliding-wind systems
High resolution radio observations with MERLIN and the VLA spatially resolve the thermal and non-thermal emission in WR147 and WR146. In both of these systems, the WR stars have massive companions. The relative positions of the radio emission and the stellar components is consistent with the non-thermal emission originating in the region where the two stellar winds in the system collide. In tot...
