Eclipses in the symbiotic system CH CYG
Abstract
In this Letter we describe observational evidence of eclipses which strongly suggest that CH Cyg is a triple system with a very high inclination. We present U and V photoelectric photometry, along with optical and ultraviolet low- and high-resolution spectroscopy taken around the inferior spectroscopic conjunctions of the red giant in the symbiotic pair of CH Cyg.
