Neutron-capture element abundances in the planetary nebula NGC 5315 from deep optical and near-infrared spectrophotometry
S. Madonna, J. García-Rojas, N. C. Sterling +5
We analyze the chemical composition of the planetary nebula (PN) NGC 5315, through high-resolution (R = 40000) optical spectroscopy with UVES at the Very Large Telescope, and mediu…
Galactic planetary nebulae with precise nebular abundances as a tool to understand the evolution of asymptotic giant branch stars
D. A. Garcia-Hernandez, P. Ventura, G. Delgado-Inglada +3
We present nucleosynthesis predictions (HeCNOCl) from asymptotic giant branch (AGB) models, with diffusive overshooting from all the convective borders, in the metallicity range Z/…
Probing O-enrichment in C-rich dust planetary nebulae
D. A. Garcia-Hernandez, P. Ventura, G. Delgado-Inglada +3
The abundance of O in planetary nebulae (PNe) has been historically used as a metallicity indicator of the interstellar medium (ISM) where they originated; e.g., it has been widely…
Oxygen enrichment in carbon-rich planetary nebulae
Gloria Delgado-Inglada, Mónica Rodríguez, Manuel Peimbert +2
We study the relation between the chemical composition and the type of dust present in a group of 20 Galactic planetary nebulae (PNe) that have high quality optical and infrared sp…
C/O abundance ratios, iron depletions, and infrared dust features in Galactic planetary nebulae
Gloria Delgado-Inglada, Mónica Rodríguez
We study the dust present in 56 Galactic planetary nebulae (PNe) through their iron depletion factors, their C/O abundance ratios (in 51 objects), and the dust features that appear…
Ionization Correction Factors for Planetary Nebulae: I- Using optical spectra
Gloria Delgado-Inglada, Christophe Morisset, Grażyna Stasińska
We compute a large grid of photoionization models that covers a wide range of physical parameters and is representative of most of the observed PNe. Using this grid, we derive new…
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…
Iron Depletion into Dust Grains in Galactic Planetary Nebulae
G. Delgado-Inglada, M. Rodríguez
We present preliminary results of an analysis of the iron depletion factor into dust grains for a sample of 20 planetary nebulae (PNe) from the Galactic bulge. We compare these res…
