THE OXYGEN ABUNDANCE IN THE SOLAR NEIGHBORHOOD

We present a homogeneous analysis of the oxygen abundance in five H regions and eight planetary nebulae (PNe) located at distances lower than 2 kpc and with available spectra of high quality. We find that both the collisionally excited lines (CELs) and recombination lines imply that the PNe are over...
