Abstract

Most accretion-powered relativistic jet sources in our Galaxy are transient X-ray binaries (XBs). Efforts to coordinate multiwavelength observations of these objects have improved dramatically over the last decade. Now the challenge is to interpret broadband spectral energy distributions (SEDs) of XBs that are well sampled in both wavelength and time. Here we focus on the evolution of the jet in their broadband spectra. Some of the most densely sampled broadband SEDs of a neutron star transient (IGR J00291+5934) are used to constrain the optically thick-thin break in the jet spectrum. For the black hole transient XTE J1550-564, infrared - X-ray correlations, evolution of broadband spectraand timing signatures indicate that synchrotron emission from the jet likely dominates the X-ray power law at low luminosities during the hard state outburst decline.
