Tracing colliding winds in the ultraviolet line orbital variability of gamma-ray binaries.
SZOSTEK A., DUBUS G. and McSWAIN M.V.
Abstract (from CDS):
We propose to use UV emission lines to detect and constrain the colliding wind region in gamma-ray binaries. We compute the expected orbital variability of P Cyg profiles depending upon the interaction geometry (set by the ratio of momentum fluxes from the winds) and the line of sight to the system. We predict little or no variability for the case of LS 5039 and PSR B1259-63, in agreement with currently available Hubble Space Telescope (HST) observations of LS 5039. However, variability between superior and inferior conjunction is expected in the case of LS I+61 303.
