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…
Analysis of chemical abundances in planetary nebulae with [WC] central stars. II. Chemical abundances and the abundance discrepancy factor
J. Garcia-Rojas, M. Peña, C. Morisset +3
(Abridged) We present the abundance analysis of 12 PNe ionized by [WC]-type stars and wels obtained from high-resolution spectrophotometric data. Our main aims are to determine the…
Exploring the effects of high-velocity flows in abundance determinations in H II regions. Bidimensional spectroscopy of HH 204 in the Orion Nebula
M. Núñez-Díaz, A. Mesa-Delgado, C. Esteban +3
We present results from integral field optical spectroscopy with the Potsdam Multi-Aperture Spectrograph of the Herbig-Haro (HH) object HH 204, with a spatial sampling of 1 x 1 arc…
Analysis of chemical abundances in planetary nebulae with [WC] central stars. I. Line intensities and physical conditions
Jorge García-Rojas, Miriam Peña, Christophe Morisset +2
(Abridged) Planetary nebulae (PNe) around Wolf-Rayet [WR] central stars ([WR]PNe) constitute a particular photoionized nebula class that represents about 10% of the PNe with classi…
Integral field spectroscopy of selected areas of the Bright Bar and Orion-S cloud in the Orion Nebula
A. Mesa-Delgado, M. Núñez-Díaz, C. Esteban +2
We present integral field spectroscopy of two selected zones in the Orion Nebula obtained with the Potsdam Multi-Aperture Spectrophotometer (PMAS), covering the optical spectral ra…
