Investigating the electron temperature of [Ar IV] in planetary nebulae using the DESIRED database
J. García-Rojas, E. Reyes-Rodríguez, J. E. Méndez-Delgado +9
(Abridged) We investigate the behaviour of the electron temperature derived from [Ar IV] lines, Te([Ar IV]), in a sample of PNe to characterize the thermal structure of high-excita…
The chemical composition of Galactic ring nebulae around massive stars
C. Esteban, A. Mesa-Delgado, C. Morisset +1
We present deep spectra of ring nebulae associated with Wolf-Rayet (WR) and O-type stars: NGC 6888, G2.4+1.4, RCW 58, S 308, NGC 7635 and RCW 52. The data have been taken with the…
The Fe/Ni ratio in ionized nebulae: clues on dust depletion patterns
Gloria Delgado-Inglada, Adal Mesa-Delgado, Jorge García-Rojas +2
We perform a homogeneous analysis of the Fe/Ni abundance ratio in eight Galactic planetary nebulae (PNe) and three Galactic H II regions that include the Orion nebula, where we stu…
