cds-question@unistra.frvisible-astronomyh-alpha-photometryWe report our initial discovery of 73 new planetary nebulae (PNe) in the Large Magellanic Cloud (LMC) following confirmatory 2dF spectroscopy on the Anglo-Australian Telescope. Preliminary candidate sources come from a 10 per cent sub-area of our new deep, high-resolution H{alpha} map of the central 25deg^2^ of the LMC obtained with the UK Schmidt Telescope. The depth of the high-resolution map was extended to R_equiv_~22 for H{alpha} (4.5x10^-17^erg/cm^2^/s/{AA}) by a process of multi-exposure median co-addition of a dozen 2-h H{alpha} exposures. The resulting map is at least 1-mag deeper than the best wide-field narrow-band LMC images currently available. This depth, combined with our selection technique, has also led to the discovery of extended asymptotic giant branch (AGB) haloes around many new and previously known LMC PNe for the first time. Once complete, our new survey is expected to triple the LMC PN population and have significant implications for the LMC PN luminosity function, kinematics, abundance gradients, chemical evolution and, via study of the AGB haloes, the initial to final mass relation for low- to intermediate-mass stars.2006MNRAS.365..401Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/365/401CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/362/689 : AAO/UKST SuperCOSMOS H{alpha} survey (Parker+, 2005)http://www-wfau.roe.ac.uk/sss/halpha : SuperCOSMOS H{alpha} survey Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/365/401https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/365/401http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/365/401https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/365/401https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/365/401http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/365/401GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/365/401/table3 (Previously known PN within the spectroscopically confirmed fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/365/401/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/365/401/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/365/401/table3?GETtext/xml+votable180.050000true80.6706667-71.31852780.005555555555555556Cone search capability for table J/MNRAS/365/401/table4 (Newly discovered PN within the spectroscopically confirmed fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/365/401/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/365/401/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/365/401/table4?GETtext/xml+votable180.050000true80.5999167-70.56552780.0055555555555555565/8272 6/33047 33052-33053 33092-33094 33096https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/365/401?format=asciiOpticaldefaultJ/MNRAS/365/401/table3Previously known PN within the spectroscopically confirmed fieldsrecnoRecord number assigned by the VizieR team.
