Atlas of monochromatic images of planetary nebulae
(EDP Sciences, 2016-08)
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 [N ii] during several observing campaigns using ...
Towards an improvement in the spectral description of central stars of planetary nebulae
(EDP Sciences, 2018-02)
Context. There are more than 3000 known Galactic planetary nebulae, but only 492 central stars of Galactic planetary nebulae (CSPN) have known spectral types. It is vital to increase this number in order to have reliable ...
Catalogue of the central stars of planetary nebulae: Expanded edition
(EDP Sciences, 2020-08)
Planetary nebulae represent a potential late stage of stellar evolution, however, their central stars (CSPNe) are relatively faint and, therefore, pertinent information is available for merely < 20 of the Galactic sample. ...

Revised Simulations of the Planetary Nebulae Luminosity Function
(IOP Publishing, 2019-12-11)
We describe a revised procedure for the numerical simulation of planetary nebulae luminosity functions (PNLFs), improving on previous work. The procedure is now based on new H-burning post-asymptotic giant branch (AGB) ...
Central stars of planetary nebulae: II. New OB-type and emission-line stars
(EDP Sciences, 2011)
On the production of He, C, and N by low- and intermediate-mass stars: A comparison of observed and model-predicted planetary nebula abundances
(Oxford University Press, 2018-01)
The primary goal of this paper is to make a direct comparison between the measured and model-predicted abundances of He, C, and N in a sample of 35 well-observed Galactic planetary nebulae (PNe). All observations, data ...
Chemical abundances of planetary nebulae in the substructures of M31. II. the extended sample and a comparison study with the Outer-disk Group
(IOP Publishing, 2018-01)
We report deep spectroscopy of 10 planetary nebulae (PNe) in the Andromeda Galaxy (M31) using the 10.4 m Gran Telescopio Canarias (GTC). Our targets reside in different regions of M31, including halo streams and the dwarf ...
