摘要：Synchrotron emission from jets produced by X-ray binaries can be detected at optical and infrared
(IR) frequencies. I show that optical/IR colour-magnitude diagrams of the outbursts of nine X-ray
binaries successfully separate thermal disc emission from non-thermal jet emission, in both black
hole and neutron star sources. A heated single-temperature blackbody is able to reproduce the
observed relations between colour and magnitude, except when excursions are made to a redder
colour than expected, which is due to jet emission. The general picture that is developed is then
incorporated into the unified picture of disc-jet behaviour in black hole X-ray binaries. At a given
position of a source in the X-ray hardness-intensity diagram, the radio, IR and optical properties
can be inferred. Similarly, it is possible to predict the X-ray and radio luminosities and spectral
states from optical/IR monitoring.
