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…
The kinematical behavior of Galactic PNe with [WC] central star
J. S Rechy-García, Miriam Peña, \and Jorge García-Rojas
High resolution spectroscopic data of a large sample of galactic planetary nebulae with [WC] central stars ([WC]PNe) are analyzed to determine their kinematical behavior. Their hel…
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…
Iron Depletion in ionized Nebulae of the Large Magellanic Cloud
G. Delgado-Inglada, M. Rodríguez, J. García-Rojas +2
We present here preliminary results of an analysis of the iron abundance in the ionized gas of three planetary nebulae and one H II region of the Large Magellanic Cloud (LMC). Thes…
Faint emission lines in planetary nebulae with a [WC] nucleus
J. García-Rojas, M. Peña, M. T. Ruiz
We present first results from the analysis of a sample of 14 planetary nebulae with [WC] nucleus with detected faint carbon and oxygen recombination lines (RLs). The results are ba…
