  • Magellanic Clouds PNe line intensities

    We present optical and ultraviolet spectroscopic observations of planetary nebulae (PNe) in the Large (LMC) and the Small Magellanic Clouds (SMC). For the visible spectra with...
  • LMC planetary nebulae positions

    We present identifications and accurate positions for about 280 planetary nebulae (PNe) in the Large Magellanic Cloud (LMC). These positions are needed for follow-up ground or...
  • Planetary nebulae radial velocities

    The table lists the heliocentric radial velocities for planetary nebulae in the direction of the Galactic bulge. The accuracy is about 2km/s. The measurements were made in June...
  • Obscured AGB in Magellanic Clouds. I.

    We have selected 198 IRAS sources in the Large Magellanic Cloud, and 11 in the Small Magellanic Cloud, which are the best candidates to be mass-loosing AGB stars (or possibly...
  • PN abundances

    Abundance determinations of about 110 planetary nebulae, which are likely to be in the Galactic Bulge are presented. Plasma diagnostics have been performed by making use of the...
  • SiO masers in OH/IR stars, proto-PN and PN

    We present a search for SiO masers towards a sample of 126 objects including OH/IR stars, proto-planetary and planetary nebulae. All objects are classified as oxygen-rich, and...
  • Planetary nebulae radial velocities

    We present a compilation of radial velocities for 867 galactic planetary nebulae (Table 2.ps [postscript format] and Table2.dat [ascii format]). Cone search capability for table...
  • V light curves of PN M2-54

    The time-series V-filter photometry of the variable central star of the Planetary Nebula M2-54 is presented.
  • O III recombination coefficients

    We calculate effective recombination coefficients for the formation of the 5g-4f lines of O III in the intermediate coupling scheme. Photoionization data for the 5g levels...
  • Iron Project. XLIV. Fe VI.

    Relativistic atomic structure calculations for electric dipole (E1), electric quadrupole (E2) and magnetic dipole (M1) transition probabilities among the first 80 fine-structure...
  • Possible new planetary nebulae in IRAS PSC

    A method for searching new possible planetary nebulae among the unidentified sources of the IRAS Point Source Catalog is described. Sources were selected according to their far...
  • Absolute fluxes and distances of PN

    We present a complete list of averaged recalibrated absolute H{beta} fluxes, global (where possible) relative He II {lambda} 4686 fluxes, 5-GHz radio flux densities, and...
  • Distances of galactic planetary nebulae

    It is well known that the IRAS colors of planetary nebulae (PNe) are very similar to blackbody colors. Taking account of this characteristic, we define a new method to obtain...
  • Near-Infrared Spectra of IC5117

    Infrared spectroscopy from 0.8 to 2.5{mu}m is presented for the planetary nebula IC5117. The emission lines of IC5117 span a wide range of ionization that includes He II, [S...
  • New SMC planetary nebulae

    Using the ESO 2.2m telescope with the 8Kx8K mosaic CCD, we have surveyed 2.8deg^2^ (~1.6{deg}x1.7{deg}) of the Small Magellanic Cloud (SMC) to search for faint planetary nebulae...
  • Spatiokinematics of NGC 1514

    New spatiokinematic observations were undertaken of the planetary nebula NGC 1514 in the [O III] line at 5007{AA} using an imaging Fabry-Perot spectrometer. Our results show an...
  • Planetary nebulae in NGC 3379 and NGC 3384

    We report on observations of four early-type galaxies performed with the Rutgers Fabry-Perot in order to search for planetary nebulae (PNe) in these systems. The aim is to use...
  • Spitzer SAGE observations of LMC PNe

    We present IRAC and MIPS images and photometry of a sample of previously known planetary nebulae (PNe) from the Surveying the Agents of a Galaxy's Evolution (SAGE) survey of the...
  • BVR light curves of NGC 6026 and 6337

    Close-binary central stars of planetary nebulae (CSPNe) provide an opportunity to explore the evolution of PNe, their shaping, and the evolution of binary systems undergoing a...
  • New classification of young planetary nebulae

    Using Hubble Space Telescope images of 119 young planetary nebulae (PNs), most of which have not previously been published, we have devised a comprehensive morphological...
