A reappraisal of the chemical composition of the Orion nebula based on VLT echelle spectrophotometry
C. Esteban, M. Peimbert, J. Garcia-Rojas +3
We present VLT UVES echelle spectrophotometry of the Orion nebula in the 3100 to 10400 A range. We have measured the intensity of 555 emission lines, many of them corresponding to…
Carbon Nitrogen, and Oxygen Galactic Gradients: A Solution to the Carbon Enrichment Problem
L. Carigi, M. Peimbert, C. Esteban +1
Eleven models of Galactic chemical evolution, differing in the carbon, nitrogen,and oxygen yields adopted, have been computed to reproduce the Galactic O/H values obtained from H I…
Carbon and Oxygen Galactic Gradients: Observational Values from HII Region Recombination Lines
C. Esteban, J. Garcia-Rojas, M. Peimbert +4
We present results of deep echelle spectrophotometry of eight Galactic HII regions located at Galactocentric distances between 6.3 and 10.4 kpc. The data have been taken with the V…
Chemical abundances of the Galactic H II region NGC 3576 derived from VLT echelle spectrophotometry
J. Garcia-Rojas, C. Esteban, M. Peimbert +3
We present echelle spectrophotometry of the Galactic H II region NGC 3576. The data have been taken with the VLT UVES echelle spectrograph in the 3100 to 10400 angstroms range. We…
