Scientific paper

An H-R diagram is drawn from the bolometric luminosities and effective temperatures of 24 symbiotic stars and compared with theoretical evolutionary tracks of Population I metal-rich stars. It is shown that the S-type and D-type symbiotic stars are classified very clearly in course of their evolution, and it is suggested that it depends on their cool components, whether it is a normal giant or an asymptotic giant branch star. The recurrent novae are less evolved than classical novae or symbiotic novae.
