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…

Electron temperatures and densities of planetary nebulae determined from the nebular hydrogen recombination spectrum and temperature and density variations
Y. Zhang, X. -W. Liu, R. Wesson +3
A method is presented to derive electron temperatures and densities of planetary nebulae (PNe) simultaneously, using the observed hydrogen recombination spectrum, which includes co…
