Infrared photometry of Galactic and MC PN
We present mid-infrared (MIR) photometry for 367 Galactic disc, bulge and Large Magellanic Cloud (LMC) planetary nebulae (PNe), determined using data acquired with the Spitzer... -
IR colours of MASH planetary nebulae
We have analysed the near-infrared (NIR) and far-infrared (FIR) colours of MASH I and MASH II (the Macquarie/AAO/Strasbourg surveys, Cat. ) planetary nebulae (PNe), using data... -
New PNe in 6 early-type galaxies
We present new planetary nebulae (PNe) positions, radial velocities and magnitudes for six early-type galaxies obtained with the Planetary Nebulae Spectrograph (PNS), along with... -
Planetary nebulae of NGC 4494
We present new Planetary Nebula Spectrograph observations of the ordinary elliptical galaxy NGC 4494, resulting in positions and velocities of 255 planetary nebulae out to seven... -
Velocities of NGC 1023 planetary nebulae
We investigate the manner in which lenticular galaxies are formed by studying their stellar kinematics: an S0 formed from a fading spiral galaxy should display similar cold... -
Complete catalog of planetary nebulae in LMC
This paper presents accurate homogeneous positions, velocities and other pertinent properties for 460 newly discovered and 169 previously known planetary nebulae (PNe) in the... -
M31 planetary nebulae velocities
We present radial velocities for a sample of 721 planetary nebulae in the disc and bulge of M31, measured using the WYFFOS fibre spectrograph on the William Herschel Telescope.... -
Kinematic survey of planetary nebulae in M31
We present a catalogue of positions, magnitudes and velocities for 3300 emission-line objects found by the Planetary Nebula Spectrograph in a survey of the Andromeda galaxy,... -
Chemical abundances for Hf 2-2
We present high-quality optical spectroscopic observations of the planetary nebula (PN) Hf 2-2. The spectrum exhibits many prominent optical recombination lines (ORLs) from... -
Galactic PNe abundances
New determinations of chemical abundances for He, N, O, Ne, Ar and S are derived for all galactic planetary nebulae (PNe) so far observed with a relatively high accuracy, in an... -
SMC emission-line objects
H{alpha} and [OIII] narrow-band, wide-field (7x7deg^2^), CCD images of the Small Magellanic Cloud were compared, and a catalogue of candidate planetary nebulae and H{alpha}... -
Abundances in Magellanic Cloud planetary nebulae
Optical spectroscopic data for 71 Planetary Nebulae (PN) in the Large and Small Magellanic Clouds have been analysed. The line fluxes have been used to determine nebular... -
Calculated chemical composition of galactic PN
The results of a study of the chemical compositions of Galactic planetary nebulae taking into account two types of inhomogeneity in the nebular gas density in their envelopes... -
JHKLM photometry of FG Sge
We present JHKLM photometric data for FG Sge, the nucleus of the planetary nebula He 1-5, obtained from 1985 to 2001, carried out on the 125cm telescope of the Sternberg... -
Distances and physical parameters of PNe
The distances and parameters of the central stars and the optical depth of envelopes in the Lyman limits of neutral hydrogen and neutral helium were determined in a... -
Galactic PNe statistical distance scale
A statistical distance scale is proposed. It is based on the correlation between the ionized mass and the radius and the correlation between the radio continuum surface... -
A 5-GHz VLA Survey of the Galactic Plane
We have used the VLA to survey the inner Galaxy (|b|<0.4{deg}, l=350-40{deg}) at 5GHz to a limiting sensitivity of between 2.5 and 10mJy. The survey has resulted in a catalog... -
PNe in NGC 5128
We present a catalog of planetary nebulae in the nearest giant elliptical galaxy NGC 5128. The catalog consists of positions and [O III]{lambda}5007 magnitudes for 785 planetary... -
Compact Radio Sources Near the Galactic Plane
The results of the extension of the 20-cm Galactic-plane survey reported by Zoonematkermani to Galactic latitudes of +/-1.8{deg} over the central region of the Milky Way are... -
M31 planetary nebulae
Finding charts and equatorial coordinates are presented for 311 planetary nebulae and for nearby reference stars in the Andromeda galaxy (M31). The standard deviation of the...
