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)...

This dataset consists of three files which reproduce data from three tables in the reference. The first file is a catalog of 159 Population I Galactic Wolf-Rayet Stars. The...

The electronic version of the catalogue referenced above includes 1143 true and probable planetary nebulae (Table 1 of publication); 347 objects which status is still unclear...

The Macquarie/AAO/Strasbourg H{alpha} Planetary Nebula Catalogue (MASH) contains 903 new true, likely and possible Galactic Planetary Nebulae (PNe) discovered from the AAO/UKST...

The He, C, N, and O abundances in more than 120 planetary nebulae (PNe) of our Galaxy and the Magellanic Clouds have been redetermined by analyzing new PNe observations. The...

We discuss the infrared (IR) (1.25-5microns) photometry of eight planetary nebulae performed in 1999-2006. For all of the nebulae under study, we have firmly established IR...

Photoelectric observations of HD 51585 (OY Gem), a B[e] star with an infrared excess and a candidate for protoplanetary nebulae, obtained with a 60-cm telescope at the Crimean...

The photometric and spectroscopic observations of IRAS 18062+2410 = V886 Her, a candidate for protoplanetary objects, in 1996-1997 are presented. The star exhibits rapid light...

We have examined central stars of planetary nebulae and symbiotic stars found in the MACHO Galactic bulge database to look for variability. We found four central stars of...

We analyze the spatial orientation of a homogeneous sample of 440 elongated Planetary Nebulae (PNe) in order to determine the orientation of their apparent major axis with...

A detailed high spectral resolution study of the spectrum of IC 418 is made for the region 3650{AA} to 10050{AA}, using the Hamilton echelle spectrograph of Lick Observatory,...

We have developed a method to determine the most reliable distances for a large group of planetary nebulae. For this purpose, we analyze the distances obtained from Gaia...

A homogeneous set of new measurements of nearly all (995 out of 1007) objects from the Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Cat. ) or in the first supplement...

We address the physical and kinematical properties of Wolf-Rayet [WR] central stars (CSs) and their host planetary nebulae (PNe). The studied sample comprises all [WR] CSs that...

The extremely accurate estimates of stellar variability and radial velocity in the Gaia Data Release 3 (Gaia DR3) have enabled us to examine the close binarity and radial...

The present work aims to build a new statistical distance scale for planetary nebulae (PNe) based on a rigorous calibration sample. The distances of the calibration sample are...

Planetary nebulae (PNe) are an important tool for studying the dynamics and chemical evolution of galaxies in the Local Universe, given their characteristic bright emission line...

List of all new planetary nebulae discovered by French amateurs (from 2016, Lastr, 91, 26) and nebulae in the mid-infrared (from 2016, LAstr, 91 36). Cone search capability for...

List of new planetary nebulae discovered by French amateurs. Cone search capability for table J/other/LAstr/80.42/table1 (Planerary nebulae candidates discovered by French...

List of all new planetary nebulae discovered by French amateurs. Cone search capability for table J/other/LAstr/136.58/table1 (List of planetary nebulae candidates) Cone search...
