We report discovery of ∼500 planetary nebulae (PNe) in the central 200 sq.deg of the Galactic Bulge from the AAO/UKST Hα survey. Confirmatory UKST 6dF fibre spectroscopy and additional follow-up on 2-m class telescopes has led to a doubling of known Bulge PNe. This new population will have important implications for the bulge PN luminosity function and will provide improved determination of abundance gradients, a better picture of chemical evolution, as well as valuable test particles for dynamical studies. © 2005 American Institute of Physics

    The emission-line analysis of ionized gaseous nebulae such as planetary nebulae (PNe) and H II regions is one of the best established methods for obtaining the abundance of elements in our own and in external galaxies. Abundance studies of PNe reveal the composition of matter returned to the...
