ROSAT Observations of CH CYG
Abstract
The symbiotic system CH Cyg was observed during the AO-2 ROSAT Guest Observer phase. CH Cyg was clearly detected, with 2900 counts in an observation period of 8200 seconds. The resulting spectrum from CH Cyg is a substantial improvement over the previous observation of CH Cyg made with the EXOSAT LE1+CMA (Leahy and Taylor, 1987). The spectrum was analyzed using XSPEC, and could not be fit with any single component model. A reasonable 2 component fit consisted of Raymond Smith plasma emission model, which fit the bulk of the spectrum, plus a power law component to fit the high energy tail. Interpretation of the spectrum will be presented. A timing analysis was also done on the photon event file. No significant variability over the observation period was detected.
