A new Planetary Nebula in the outer reaches of the Galaxy
K. Viironen, A. Mampaso, R. L. M. Corradi +11
A proper determination of the abundance gradient in the Milky Way requires the observation of objects at large galactiocentric distances. With this aim, we are exploring the planet…
IPHAS extinction distances to Planetary Nebulae
C. Giammanco, S. E. Sale, R. L. M. Corradi +13
The determination of reliable distances to Planetary Nebulae (PNe) is one of the major limitations in the study of this class of objects in the Galaxy. The availability of new phot…
IPHAS and the symbiotic stars. II. New discoveries and a sample of the most common mimics
R. L. M. Corradi, M. Valentini, U. Munari +19
In a previous paper [arXiv:0712.2391], we presented the selection criteria needed to search for symbiotic stars in IPHAS, the INT Halpha survey of the Northern Galactic plane. IPHA…
Candidate planetary nebulae in the IPHAS photometric catalogue
K. Viironen, R. Greimel, R. L. M. Corradi +12
Context. We have carried out a semi-automated search for planetary nebulae (PNe) in the INT Photometric H-Alpha Survey (IPHAS) catalogue. We present the PN search and the list of s…
New Young Planetary Nebulae in IPHAS
K. Viironen, A. Mampaso, R. L. M. Corradi +12
We search for very small-diameter galactic planetary nebulae (PNe) representing the earliest phases of PN evolution. A recently published IPHAS catalogue of Ha-emitting stars provi…
The warm ionized medium in spiral galaxies
L. M. Haffner, R. -J. Dettmar, J. E. Beckman +6
This article reviews observations and models of the diffuse ionized gas that permeates the disk and halo of our Galaxy and others. It was inspired by a series of invited talks pres…
