Generalized energy balance method for the determination of central star parameters and optical thickness of a planetary nebula

Astrophysics and Space Science, 1995
A method is proposed allowing a quick self-consistent determination of both the central star parameters (effective temperature, surface gravity, stellar massetc.) and the optical thickness of a planetary nebula (PN). The method is a generalization of the well-known energy balance method. The method has been calibrated and tested using a photoionization
