Radio-frequency observations of galactic X-ray sources. II.
Abstract
Six galactic low-mass X-ray binary stars were surveyed with the VLA at 4.8 GHz to search for objects with morphologies similar to that of Sco X-1. Two objects, 2129+470 and 2142+380 (Cyg X-2) were detected at the 1 mJy level; their radio emission is thermal. Variability in the quiescent radio state has been established for 0620-003. None of the sources exhibited a radio morphology similar to the triple-source structure of Sco X-1.
