Radio observations of the X ray binary Cygnus X-2
Abstract
The observations of the x ray binary Cyg X-2 are reported. They were performed with Ginga X-ray satellite, IUE and ground based optical and radio instruments, in 1988 June 10 to 14 and 1988 October 6 to 9. An apparent correlation between the behavior of this object in the observed wavelengh regions (1.49, 4.9 and 8.4) is established. Data supports the conclusion that Cyg X-2 has radio quiet states. Two hypothetical scenarios for a relationship between radio and x ray emission in Cyg X-2 are discussed.
