Detection of new planetary nebulae by IPHAS, the Hα survey of the North Galactic plane
Parker, Q. A.
IPHAS is an ongoing Hα imaging survey of the North Galactic plane. When completed, it is expected to discover several hundred new Galactic planetary nebulae, in addition to a huge number of Hα emitters. We present here the project, the methods used to search for compact and extended ionized nebulae, and some preliminary results about the ∼100 new candidate planetary nebulae identified so far.
