Spectroscopy of Planetary Nebulae in Sextans A and Sextans B
Sextans A and Sextans B are two dIr galaxies situated in the outskirts of the Local Group (LG), in which both PNe and H II regions have been detected (Jacoby & Lesser 1981, Magrini et al. 2002, 2003). We present spectroscopic observations of PNe and HII regions in these two galaxies (obtained with the VLT) Preliminary results about PNe physico-chemical properties are presented.
