PNE AS OBSERVATIONAL CONSTRAINTS IN CHEMICAL EVOLUTION MODELS FOR NGC 6822
We present chemical evolution models for the dwarf irregular galaxy NGC6822, using as observational constraints chemical abundances of planetary nebulae (PNe) and HII regions derived from both, collisionally excited lines (CELs) and recombination lines (RLs) methods. We built two models that reprodu...
