A New Population of Planetary Nebulae Discovered in the LMC
Abstract
We report our discovery of 471 planetary nebulae (PNe) in the central 25~deg$2$ region of the Large Magellanic Cloud (LMC) following confirmatory two-degree Field (2dF) spectroscopy on the Anglo-Australian Telescope (AAT). Candidate emission sources were discovered using deep, high resolution UKST stacked Short Red (SR) and H$α$ images which go deeper than any previously available. The two digitized stacks were then merged to reveal emission sources. The new PNe have implications for the LMC PN luminosity function, kinematics, abundance gradients, chemical evolution and the initial to final mass relation for low to intermediate mass stars via the AGB halos revealed on the H$α$ map. Excitation classes are presented.
