Significance Both CH Cygnii and R Aquarii are symbiotic star systems that have been well studied at various wavelengths.
Symbiotic stars are binary systems that consist of a red giant and a smaller, hotter companion.
Matter from the red giant is transferred to its companion, forming an accretion disk and often resulting in powerful eruptions. CH Cygnii and R Aquarii are the only two symbiotic star systems from which a pair of radio jets emanate. This similarity makes them ripe for comparison. He subsequently notified Jan Hollis, who has great interest in the object. Before doing an analysis of the data, it was first necessary to see if one could duplicate the CH Cygnii results.
