摘要: The three galactic X-ray binaries that show evidence for jets, Sco X-1, Cyg X-3, and SS433 are examined. is the only source shows rich jet features in all wavelengths from radio to gamma rays; jets of X-1 X-3 evident region. Observational systems, as binaries, summarised compared. A possible common model central engine, involving a fast spinning neutron star with weak surface field (B s ≲109 gauss), outlined.
