Abstract

We survey a number of RS CVn systems to determine the frequency and nature of circumstellar matter in these chromospherically active binaries. A growing body of data suggests that large extended regions of cool, prominence-like matter may be a common phenomenon in these systems. Our targets are eclipsing systems as the established geometries and occultations are useful probes for such extended material. In this paper we discuss our methods and present the results of our survey and our spectroscopic phase monitoring of these systems. We find extended material in eight of the ten systems on our present survey.
