Planetary Nebulae in Local-Group Galaxies. I. Identifications in NGC 185, NGC 205, and NGC 221
Abstract
We present identifications of planetary nebulae in NGC 185 (4), NGC 205 (12), and NGC 221(10). We identified the nebulae by isolating their O m] and Ha emission lines. These nebulae will allow us to directly determine chemical abundances in elliptical galaxies in the Local Group. Subject headtngs: galaxies, individual - planetary nebulae
