The symbiotic system CH Cygni: An analysis of the shocked nebulae at different epochs

Rafanelli, P.; Angeloni, R.; Contini, M.

We analyse the line and continuum spectra of the symbiotic system CH Cygni. We adopt the colliding-wind model to explain the symbiotic system at different phases. Peculiar observed features such as flickering, radio variation, X-ray emission, as well as the distribution of the nebulae and shells throughout the system are investigated by modelling …
