LOCATION OF PN CENTRAL STARS ON THE HR DIAGRAM
J. O. Cazetta, W. J. Maciel
Astron. Astrophys. 290, 936-940 (1994) Galactic planetary nebulae (PN) form a complex system, which includes objects with different characteristics and evolutionary stage. The location of a sample of galactic PN central stars on the HR diagram is attempted, in order to investigate the correspondence of the PN properties such as chemical composition, space distribution and kinematics, with the main sequence masses of their progenitor stars.
