Symbiotic binaries are often divided into two sub-types based on the nature of the continuum in their spectra. "S-type" systems have a stellar continuum since the giant component is not obscured. "D-type" systems are surrounded by optically thick dusty nebulosity and the star itself is not directly visible. D-type systems tend to contain a Mira variable or other long period variable star. Some symbiotic stars have jets which are a collimated outflow of material. These typically are
