Description
Only 5 Planetary Nebulae (PNe) among the previously known Galactic Open Cluster (OC) population of ∼ 1,100 are known to date. They are extremely valuable because their properties can be directly linked to their progenitor stars, something that cannot be done for PNe in the general field. Since the first data release of the GAIA astrometric satellite, ≈7,200 new OC candidates have been identified. This offers fresh motivation to search them for potential PNe. On a statistical basis alone, given those OC-PN pairs we have already found, we might expect a further 30 OC-PN pairs to be present. We have searched all the latest large OC catalogues for new OC/PN associations and recovered 2 promising new candidates.
