    • Candidate planetary nebulae in the IPHAS photometric catalogue 

      Viironen, K.; Greimel, R.; Corradi, R.L.M.; Mampaso, A.; Rodriguez, M.; Sabin, L.; Delgado-Inglada, G.; Drew, J.E.; Giammanco, C.; Gonzalez-Solares, E.; Irwin, M.J.; Miszalski, B.; Parker, Q.A.; Rodriguez-Flores, E.R.; Zijlstra, A.A. (2009)
      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 selected candidates. We cross correlate the ...
    • IPHAS and the symbiotic stars. II. New discoveries and a sample of the most common mimics 

      Corradi, R.L.M.; Valentini, M.; Munari, U.; Drew, J.E.; Rodriguez-Flores, E.R.; Viironen, K.; Greimel, R.; Santander-Garcia, M.; Sabin, L.; Mampaso, A.; Parker, Q.A.; De Pew, K.; Sale, S.E.; Unruh, Y.C.; Vink, J.S.; Rodriguez-Gil, P.; Barlow, M.J.; Lennon, D.J.; Groot, P.; Giammanco, C.; Zijlstra, A.A.; Walton, N.A. (2010)
      Context. Knowledge of the total population of symbiotic stars in the Galaxy is important for understanding basic aspects of stellar evolution in interacting binaries and the relevance of this class of objects in the formation ...
    • IPHAS extinction distances to planetary nebulae 

      Giammanco, C.; Sale, S.E.; Corradi, R.L.M.; Barlow, M.J.; Viironen, K.; Sabin, L.; Santander-Garcia, M.; Frew, D.J.; Greimel, R.; Miszalski, B.; Phillipps, S.; Zijlstra, A.A.; Mampaso, A.; Drew, J.E.; Parker, Q.A.; Napiwotzki, R. (2011)
      Aims. The determination of reliable distances to planetary nebulae (PNe) is a major difficulty in the study of this class of objects in the Galaxy. The availability of new photometric surveys such as IPHAS (the INT/WFC ...
    • The Necklace : equatorial and polar outflows from the binary central star of the new planetary nebula IPHASX J194359.5+170901 

      Corradi, R. L. M.; Sabin, L.; Miszalski, B.; Rodriguez-Gil, P.; Santander-Garcia, M.; Jones, D.; Drew, J.E.; Mampaso, A.; Barlow, M.J.; Rubio-Diez, M. M.; Casares, J.; Viironen, K.; Frew, D. J.; Giammanco, C.; Greimel, R.; Sale, S. E. (2011-01)
      IPHASX J194359.5+170901 is a new high-excitation planetary nebula with remarkable characteristics. It consists of a knotty ring expanding at a speed of 28 km s-1, and a fast collimated outflow in the form of faint lobes ...
    • A new planetary nebula in the outer reaches of the galaxy 

      Viironen, K.; Mampaso, A.; Corradi, R.L.M.; Drew, J.E.; Frew, D.J.; Giammanco, C.; Greimel, R.; Liimets, T.; Lindberg, J.E.; Rodriguez, M.; Sabin, L.; Sale, S.E.; Wilson, P.A.; Zijlstra, A.A. (2011)
      Aims. 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 planetary nebula population towards the ...
    • New young planetary nebulae in IPHAS 

      Viironen, K.; Mampaso, A.; Corradi, R.L.M.; Rodriguez, M.; Greimel, R.; Sabin, L.; Sale, S.E.; Unruh, Y.C.; Delgado-Inglada, G.; Drew, J.E.; Giammanco, C.; Groot, P.; Parker, Q.A.; Sokoloski, J.; Zijlstra, A.A. (2009)
      Aims. We search for very small-diameter galactic planetary nebulae (PNe) representing the earliest phases of PN evolution. The IPHAS catalogue of H-emitting stars provides a useful basis for this study since all sources ...
