Scientific paper

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.
