X-ray and Radio Emission from Colliding Stellar Winds
The collision of the hypersonic winds in early-type binaries produces shock heated gas, which radiates thermal X-ray emission, and relativistic electrons, which emit nonthermal radio emission. We review our current understanding of the emission in these spectral regions and discuss models which have been developed for the interpretation of this emission. Physical processes which affect the resu...
متن کاملX-ray emission lines from inhomogeneous stellar winds
It is commonly adopted that X-rays from O stars are produced deep inside the stellar wind, and transported outwards through the bulk of the expanding matter which attenuates the radiation and affects the shape of emission line profiles. The ability of the X-ray observatories Chandra and XMM-Newton to resolve these lines spectroscopically provided a stringent test for the theory of the X-ray pro...
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 کاملThe interactions of winds from massive young stellar objects: X-ray emission, dynamics, and cavity evolution
2D axis-symmetric hydrodynamical simulations are presented which explore the interaction of stellar and disk winds with surrounding infalling cloud material. The star, and its accompanying disk, blow winds inside a cavity cleared out by an earlier jet. The collision of the winds with their surroundings generates shock heated plasma which reaches temperatures up to ∼ 10 K. Attenuated X-ray spect...
متن کاملParticle Re - Acceleration in Colliding Winds Systems ? Radio , X - ray , and γ - ray Emission Models of WR 140
We present calculations of the spatial and spectral distribution of the radio, X-ray and γ-ray emission from shock accelerated electrons in the wind-collision region (WCR) of WR140. 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 conjunction with the radio emission to constrain the mass...
