ROSAT PSPC OBSERVATIONS OF THE SYMBIOTIC CH CYGNI

CH Cyg is a symbiotic stellar system, recently (Hinkle et al.) discove red to be a triple, with a third low-mass star in a 14 year orbit abou t the central pair. The complex behavior of CH Cyg, which includes cyc les of activity and quiescence, can be mainly attributed to the inner binary. CH Cyg was first discovered to be an X-ray source by EXOSAT ob servations (Leahy & Taylor). Recent followup X-ray observations have b een made with the ROSAT X-ray telescope and PCSC detector. An analysis of the X-ray spectrum yields two emission components. A time variabil ity analysis of CH Cyg shows no variability detected in the present ob servations.
