Abstract: X-ray binaries are stellar systems in which X-ray emission results from accretion from a normal star onto a compact object, i.e., a neutron star or black hole. Radio emission is associated both with X-ray outbursts, and with more stable conditions when the X-rays are dominated by a persistent hard power-law component. The VLBA has played a crucial role in studying these systems, by allowing detailed AU-scale imaging. This has allowed direct measurements of morphologies, orientations, expansion speeds, and scattering sizes, as well as detailed astrometric and proper motion studies. We review results from our group in this area, namely observations of H1743-322 and SS433.
