Descripción
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 selected candidates with a number of existing infrared
galactic surveys in order to gain further insight into the nature of the
candidates. Spectroscopy of a subset of objects is used to estimate the
number of PNe present in the entire candidate list. Aims: The
overall aim of the IPHAS PN project is to carry out a deep census of PNe
in the northern Galactic plane, an area where PN detections are clearly
lacking. Methods: The PN search is carried out on the IPHAS
photometric catalogue. The candidate selection is based on the IPHAS and
2MASS/UKIDSS colours of the objects and the final candidate selection is
made visually. Results: From the original list of ~600 million
IPHAS detections we have selected a total of 1005 objects. Of these, 224
are known objects, leaving us with 781 PN candidates. Based on the
initial follow-up spectroscopy, we expect the list to include very young
and proto-PNe in addition to genuine, normal PNe (~16%) and emission
line objects other than PNe. We present additional criteria to select
the most probable PN candidates from our candidate list.

Nebulosas Bipolares
Nuestro proyecto persigue tres objetivos principales: 1) Determinar las condiciones físico-químicas de las nebulosas planetarias con geometría bipolar y de las nebulosas alrededor de estrellas simbióticas. El fin es entender el origen de la bipolaridad y poner a prueba los modelos teóricos que intentan explicar la morfología y la cinemática nebular
