Abstract (from CDS):

We report the first resolved bispectrum speckle interferometry of the symbiotic binary CH Cyg. The measured component separation, ρ = 42 ± 2mas, is consistent with the one derived from the known spectroscopic orbit and distance. In particular, our result implies a total mass of the binary of Mt= Mg+ Mwd= 3.7+3.5–1.7M☉, which is in good agreement with the value Mt= 2.7+1.2–0.6M☉ derived from the spectroscopic orbit solution for the red giant and evolutionary constraints. We also show that the radio jets and the bipolar outflow are not orthogonal to the orbital plane of the binary system.
