Can we believe the strong-line abundances in giant HII regions and emission-line galaxies?
Abstract
This review is not a compendium of strong-line methods to derive abundances in giant HII regions. It is mostly intended for readers who wish to use such methods but do not have a solid background on the physics of HII regions. It is also meant to encourage those using abundance results published in the literature to think more thoroughly about the validity of these results.
