GTC Spectroscopic Surveys of Planetary Nebulae in the Milky Way and M31
Xuan Fang, Haomiao Huang, Martin A. Guerrero +4
We report spectroscopic surveys of planetary nebulae (PNe) in the Milky Way and Andromeda (M31), using the 10.4-m Gran Telescopio Canarias (GTC). The spectra are of high quality an…
Chemical Abundances of Planetary Nebulae in the Substructures of M31
Xuan Fang, Ruben Garcia-Benito, Martin A. Guerrero +4
We present deep spectroscopy of planetary nebulae (PNe) that are associated with the substructures of the Andromeda Galaxy (M31). The spectra were obtained with the OSIRIS spectrog…
Abundances of s-process elements in planetary nebulae: Br, Kr & Xe
Y. Zhang, R. Williams, E. Pellegrini +5
We identify emission lines of post-iron peak elements in very high signal-to-noise spectra of a sample of planetary nebulae. Analysis of lines from ions of Kr and Xe reveals enhanc…
Integrated spectrum of the planetary nebula NGC 7027
Y. Zhang, X. -W. Liu, S. -G. Luo +2
We present deep optical spectra of the archetypal young planetary nebula (PN) NGC 7027, covering a wavelength range from 3310 to 9160 A. The observations were carried out by unifor…
Helium recombination spectra as temperature diagnostics for planetary nebulae
Y. Zhang, X. -W. Liu, Y. Liu +1
Electron temperatures derived from the \ion{He}{1} recombination line ratios, designated (\ion{He}{1}), are presented for 48 planetary nebulae (PNe). We study the effect…
Observations and 3D photoionisation modelling of the Wolf-Rayet planetary nebula NGC 1501
Barbara Ercolano, R. Wesson, Y. Zhang +4
Deep optical spectra of the high excitation planetary nebula NGC 1501 and its W04 central star are presented. A recombination line abundance analysis of the central star's emission…
