Confirmed PN in M87 outer regions
We present a kinematic study of a sample of 298 planetary nebulas (PNs) in the outer halo of the central Virgo galaxy M87 (NGC 4486). The line-of-sight velocities of these PNs... -
Planetary nebulae monochromatic images atlas
We present an atlas of more than one hundred original images of planetary nebulae (PNe). These images were taken in a narrow-band filter centred on the nebular emission of the... -
Kn 26, a new quadrupolar planetary nebula
Once classified as an emission line source, the planetary nebula (PN) nature of the source Kn 26 has only recently been recognized in digital sky surveys. To investigate the... -
Catalog of NGC 300 planetary nebula candidates
[OIII]5007 Angstroms on-band off-band images, obtained with the Very Large Telescope (VLT) and FORS2 spectrograph in two zones (center and outskirts) of the spiral galaxy... -
Interacting planetary nebulae
We discuss the classification and orientation of planetary nebulae that interact with the interstellar medium throughout the Milky Way. A sample of 117 confirmed interacting... -
NGC 1399 planetary nebula velocities
Using a counter-dispersed slitless spectroscopy technique, we detect and measure the line-of-sight velocities of 187 planetary nebulae (PNe) around one of the nearest cD... -
Observing log of 9 planetary nebulae
We present observations of the infrared fine-structure lines of [Si II] (34.8{mu}m), [O I] (63.2 and 145.5{mu}m) and [C II] (157.7{mu}m) obtained with the ISO SWS and LWS... -
Coordinates of Galactic planetary nebulae
The table is a compilation of the positions of 1312 Galactic Planetary Nebulae (PNe). We have used the 2nd generation of the Guide Star Catalogue (GSC-II, Cat. ) as a reference... -
Angular dimensions of 312 planetary nebulae
We present the results of direct measurements done on H{alpha} (or H{alpha}+[NII]) images of 312 planetary nebulae. For each planetary nebulae deconvolved FWHM and resolution... -
Spectrophotometry of planetary nebulae
Spectrohotometric observations at high signal-to-noise ratio for a sample of 62 planetary nebulae are presented, together with the plasma and abundance analyses. The objects... -
PNe and HII in NGC 300
We report a search for planetary nebulae and H II regions in the central part of the late-type spiral NGC 300, using a CCD and the on-band/off-band filter technique. The total... -
Radio observations of South. PN Candidates
IRAS sources having IR colours typical of planetary nebulae and located outside the Galactic bulge were observed in the radio continuum at 6cm with the Australian Compact Array...
