DETERMINATION OF THE GALACTIC ROTATION CURVE BASED ON PLANETARY NEBULAE
C. M. Dutra, W. J. Maciel
Rev. Mexicana Astron. Astrofis. 21, 264-268 (1990) Planetary nebulae of types I, IIa, and IIb are considered in order to determine the galactic rotation curve. It is shown that the curves defined by the first two types do not differ substantially from the one derived on the basis of young population I objects, such as CO-HII molecular complexes.
