A wealth of new planetary nebulae from the IPHAS survey
Abstract
A systematic search for discrete nebulae from IPHAS, the 1800 square degree H-alpha survey of the Northern Galactic Plane carried out at La Palma Observatory, is currently underway.
Here we present the first major installment of the "IPHAS Catalogue of Extended Nebulae". This includes a complete census of emission-line nebulae in 320 square degrees toward the inner regions of the Galaxy. In this area, five hundred emission nebulae have been catalogued including 100 known planetary nebulae (PNe), and 150 new IPHAS candidate PNe.
A vigorous programme of spectroscopic confirmation of IPHAS candidate PNe over the entire survey area is underway using a number of telescopes worlwide. So far, around one hundred new PNe have been spectroscopically confirmed (Viironen et al. 2008, 2009, 2011, Corradi et al. 2011, Sabin et al. 2011, Ramirez et al. 2011). Their main properties, some outstanding examples, as well as the relevance of the IPHAS survey to determine the total PN population in the Galactic disc and its chemical gradient will be discussed.
