Radio , 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 کاملX-ray Emission from O Stars
Young O stars are strong, hard, and variable X-ray sources; properties that strongly affect their circumstellar and galactic environments. After ≈ 1 Myr, these stars settle down to become steady sources of soft X-rays. I will use high-resolution X-ray spectroscopy and MHD modeling to show that young O stars like θ Ori C are well explained by the magnetically channeled wind shock scenario. After...
متن کاملCorrelation between the TeV γ-ray and X-ray emission from an accreting X-ray binary
The signal strength of TeV gamma rays from the accreting X-ray binary Cen X-3 shows evidence for correlation with both the RXTE/ASM and the BATSE X-ray signal strengths. The time scale for the variability of the gamma rays may be similar to that of X-rays and as short as a day.
متن کاملCorrelation between the X-ray and Tev Gamma Ray Emission from an Accreting X-ray Binary
Measurements of the signal strength of TeV gamma rays from the accreting X-ray binary Cen X-3 show evidence for correlation with both the RXTE/ASM and the BATSE X-ray signal strengths. There are indications that the time scale for the variability of the gamma rays may be similar to that of X-rays and as short as a day. These features of the X-ray and TeV emission from an accreting binary show m...
متن کاملPolarised infrared emission from X-ray binary jets⋆
Near-infrared (NIR) and optical polarimetric observations of a selection of X-ray binaries are presented. The targets were observed using the Very Large Telescope and the United Kingdom Infrared Telescope. We detect a significant level (3σ) of linear polarisation in four sources. The polarisation is found to be intrinsic (at the > 3σ level) in two sources; GRO J1655–40 (∼ 4–7% in H and Ks-bands...
