Radio Emission from Conical Jets Associated with X-Ray Binaries
Abstract
Kinematic and physical models for the evolution of synchrotron radio emission in conical twin jets are derived and are shown to have most of the characteristics needed to explain the wide variety of radio properties in X-ray binaries; the spatial distribution of SS 433's radio jets; periodic emission from LSI + 61 deg 303 and quiescent Cyg X-3; and the stable quiescent emission from Cyg X-1, Cyg X-2, and Sco X-1. These models assume adiabatic expansion and are distinguished from other jet models by the dominance of lateral motions due to free or slowed expansion of a collimated flow of a hot, X-ray emitting gas. A laterally expanding environment, behaving like a supernova remnant expanding in a cylindrical geometry, is the location of steady production of relativistic plasma, and, when the relativistic plasma pressure is dominant, this geometry can provide the spherically expanding plasmoids causing radio flares.
