We consider the possibility of cluster membership for 13 planetary nebulae that are located in close proximity to open clusters lying in their lines of sight. The short lifetimes and low sample size of intermediate-mass planetary nebulae with respect to nearby open clusters conspire to reduce the probability of observing a true association. Not surprisingly, line-of-sight coincidences almost certainly exist for 7 of the 13 cases considered. Additional studies are advocated, however, for six… 
Investigating potential planetary nebula/cluster pairs
Context. Fundamental parameters characterizing the end-state of intermediate-mass stars may be constrained by discovering planetary nebulae (PNe) in open clusters (OCs). Cluster membership may be
Discovery of an open cluster with a possible physical association with a planetary nebula
We report the discovery of a new open cluster (OC) in the Galaxy at (, =- 167°0 and b = -1°0. Its field includes the planetary nebula (PN) PK 167-0.1. We study the possible associations of the PN/OC
We report the results of an [O iii] λ5007 spectroscopic survey for planetary nebulae (PNe) located within the star clusters of M31. By examining R ∼ 5000 spectra taken with the WIYN+Hydra
New Candidate Planetary Nebulae in Galactic Globular Clusters from the VVV Survey
Only four globular cluster planetary nebulae (GCPN) are known so far in the Milky Way. About 50 new globular clusters have been recently discovered toward the Galactic bulge. We present a search for
AAOmega radial velocities rule out current membership of the planetary nebula NGC 2438 in the open cluster M46
We present new radial velocity measurements of 586 stars in a one-degree field centred on the open cluster M46, and the planetary nebula NGC 2438 located within a nuclear radius of the cluster. The
Catalogue of the central stars of planetary nebulae
Planetary nebulae represent a potential late stage of stellar evolution, however, their central stars (CSPNe) are relatively faint and, therefore, pertinent information is available for merely < 20%
Ionization structure of multiple-shell planetary nebulae - I. NGC 2438
Context. In recent times an increasing number of extended haloes and multiple shells around planetary nebulae have been discovered. These faint extensions to the main nebula trace the mass-loss
Catalogue of central stars of planetary nebulae: Expanded edition
Planetary nebulae represent a potential late stage of stellar evolution, however the central stars (CSPNe) are relatively faint and therefore pertinent information is merely available for <20% of the
Photoelectric search for peculiar stars in open clusters. XV. Feinstein 1, NGC 2168, NGC 2323, NGC 2437, NGC 2547, NGC 4103, NGC 6025, NGC 6633, Stock 2, and Trumpler 2
The chemically peculiar (CP) stars of the upper main sequence are mainly characterized by strong overabundances of heavy elements. Two subgroups (CP2 and CP4) have strong local magnetic fields which
Solving the distance discrepancy for the open cluster NGC 2453
Context. The open cluster (OC) NGC 2453 is of particular importance since it has been considered to host the planetary nebula (PN) NGC 2452, however their distances and radial velocities are strongly


In two known cases, objects identified as planetary nebulae are seen in projection upon clusters of stars: the small nebula found in the globular cluster M 15, and NGC 2438 which is seen within the
The open cluster NGC 2818 and its associated planetary nebula
New CCD UBV photometry of the open cluster NGC 2818 central region indicates that previously derived values of distance and reddening for the cluster have been considerably overestimated, leading to
Planetary nebula distances re-examined: an improved statistical scale
The distances of planetary nebulae (PNe) are still quite uncertain. Although observational estimates are available for a small proportion of PNe, based on statistical parallax and the like, such
The distance scale of planetary nebulae
By collecting distances from the literature, a set of 73 planetary nebulae with mean distances of high accuracy is derived. This sample is used for recalibration of the mass-radius relationship, used
Detection of Ks-excess stars in the 14Myr open cluster NGC4755
We derive the structure, distribution of MS and PMS stars and dynamical state of the young open cluster NGC 4755. We explore the possibility that, at the cluster age, some MS and PMS stars still
Version 2000 of the Catalogue of Galactic Planetary Nebulae
The “Catalogue of Galactic Planetary Nebulae (Version 2000)” appears in Abhandlungen aus der Hamburger Sternwarte, Band XII in the year 2001. It is a continuation of CGPN(1967) and contains 1510
Cepheids in LMC clusters and the period-age relation
We have made a new comparison of the positions of Cepheids and clusters in the LMC and constructed a new empirical period-age relation taking into account all available data on Cepheids in the LMC
Study of the planetary nebula NGC 2438 I. Spectroscopy of the nebula and of some cluster stars
We found 36 emission lines in the spectrum of the planetary nebula NGC 2438, and we determined its exc. class to be about 6–7. The nebular RVhel = 60.3 ± 3.6 km/s (5 spectra) is in agreement with
A study of spatial structure of galactic open star clusters
In order to study the relation between the core and corona in galactic star clusters, the spatial structure of 38 rich open star clusters has been studied using radial density proles derived from the
Binary Central Stars
Only a handful of binary central stars of planetary nebulae (PNe) are known today, due to the difficulty of detecting their companions. Preliminary results from radial velocity surveys, however, seem
