K 4-47: a planetary nebula excited by photons and shocks
D. R. Goncalves, A. Mampaso, R. L. M. Corradi +3
K 4-47 is an unusual planetary nebula composed of a compact high-ionization core and a pair of low-ionization knots. Long-slit medium-resolution spectra of the knots and core are a…
Spectroscopy of Planetary Nebulae in Sextans A and Sextans B
Laura Magrini, Pierre Leisy, Romano L. M. Corradi +3
Sextans A and Sextans B are two dIr galaxies situated in the outskirts of the Local Group (LG), in which both PNe and H II regions have been detected (Jacoby & Lesser 1981, Magrini…
Chemical Abundances of Planetary Nebulae in M33
L. Magrini, M. Perinotto, A. Mampaso +1
Using spectroscopic data presented in Magrini et al. (2003), we have analyzed with the photoionization code CLOUDY 94.00 (Ferland et al. 1998) 11 Planetary Nebulae belonging to the…
