Abstract

A list of 1820 objects, each of them called at least once a planetary nebula, has been inspected; 1143 of them have been classified as true or probable planetary nebulae by the authors of the catalogue (Tables 1); 347 objects, the status of which is still unclear, were classified among the “possible” planetary nebulae (Table 2).; 330 objects have been rejected, on various grounds, from the community of planetary nebulae (Table 3).

... We have taken the nebular Hβ fluxes and electron densities from Stasinska & Szczerba (1999). Emission-line fluxes of [O III] and He II are obtained from Strasbourg-ESO Catalogue of Galactic PNe (Acker et al. 1992). Distances to PNe in our sample are from Frew, Parker & Bojicic (2016;FPB16 hereafter) which were derived using H α surface brightness of the nebula versus its radius relationship. ...
... [WR] and wels-PNe are concentrated near the Galactic plane, however, normal PNe are commonly seen at higher latitudes. This is in contrast with the suggestion given by Acker et al. (1996). ...
... The distribution of nebular C/O ratio of [WR] PNe is similar with the other PNe as found by Gorny & Stansinska (1995). However, many of the wels appear in Mendez (1991) are oxygen-rich stars and are related to variable stars with oxygen-rich circumstellar shells (Acker et al. 1996). The grain chemistry is not known for many of the PNe in our sample. ...

We report the infrared (IR) properties of planetary nebulae (PNe) with Wolf–Rayet (WR) type and wels central stars known to date and compare them with the IR properties of a sample of PNe with H-rich central stars. We use near-, mid-, and far-IR photometric data from archives to derive the IR properties of PNe. We have constructed IR colour–colour diagrams of PNe using measurements from 2MASS, IRAS, WISE, and Akari bands. [WR] PNe have a larger near-IR emission from the hot dust component and also show a tendency for stronger 12 μm emission as compared to the other two groups. Cool asymptotic giant branch dust properties of all PNe are found to be similar. We derived the dust colour temperatures, dust masses, dust-to-gas mass ratios, IR luminosities, and IR excess (IRE) of PNe for these three groups. [WR] PNe and wels-PNe tend to have larger mean values for dust mass when compared to the third group. The average dust-to-gas mass ratio is found to be similar for the three groups of PNe. While there is a strong correlation of dust temperature and IR luminosity with the age for the three groups of PNe, the dust mass, dust-to-gas mass ratios, and IRE are found to be non-varying as the PNe evolve. [WR] PNe and wels-PNe show very similar distribution of excitation classes and also show similar distribution with Galactic latitude.

This review provides useful background and information on how we find, vet and compile Planetary Nebulae (PNe) candidates and verify them. It presents a summary of the known Galactic PNe population and their curation in the Hong Kong/AAO/Strasbourg/Hα PNe catalogue, “HASH”. It is a simple introduction for anyone interested in working with PNe, including postgraduate students entering the field and for more general interest too.

Evolution of post-AGB stars is extremely fast. They cross the HR diagram vertically on a timescale of hundreds to some ten thousands of years to reach maximum temperature in their lifetime. This is reflected in an increasing excitation of planetary nebulae on a timescale of years and decades. Since evolutionary timescale of post-AGB stars is very sensitive to their mass, observed changes can be used to determine model dependent central star masses. If an additional parameter is determined (e.g. luminosity or dynamic age), the observed evolution of planetary nebulae can be utilized for observational verification of theoretical models.
