Abstract

In this review I summarise the observational connections between accretion and relativistic outflows - jets - in X-ray binaries. I argue that jets are likely to be a fairly ubiquitous property of X-ray binaries as a whole, an assetion which can be tested by further observations of the Atoll-type X-ray binaries. I discuss broad patterns that are emerging from these observational studies, such as a correlation between ‘hard’ X-ray states and the presence of radio emission, and the related anti-correlation between jet strength and mass-accretion rate as inferred from X-ray studies alone. I briefly discuss possible future directions for research and compare X-ray binary jets to those from Active Galactic Nuclei and Gamma Ray Bursts.
