Optical spectra of new low-excitation PNs

DOI

We present mid-resolution spectroscopic observations of four new planetary nebula (PN) candidates selected from the INT/WFC Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS) and Deep Sky Hunter (DSH) catalogues. The PN status of these objects was confirmed by mid-resolution spectra. Based on the locations of these objects in the log(H-alpha/[NII]) versus log (H-alpha/[SII]) diagnostic diagram, these sources are evolved low- excitation PNs.
