The chemical composition of the Galactic regions M8 and M17. A revision based on deep VLT echelle spectrophotometry
J. Garcia-Rojas, C. Esteban, A. Peimbert +3
We present new echelle spectrophotometry of the Galactic H II regions M8 and M17. The data have been taken with the VLT UVES echelle spectrograph in the 3100 to 10400 angstroms ran…
The localized chemical pollution in NGC 5253 revisited: Results from deep echelle spectrophotometry
A. R. Lopez-Sanchez, C. Esteban, J. Garcia-Rojas +2
We present echelle spectrophotometry of the blue compact dwarf galaxy (BCDG) NGC 5253. The data have been taken with the Very Large Telescope UVES echelle spectrograph in the 3100…
The Calibration of the O/H Abundance Indicators for Extragalactic H II Regions Based on O II Recombination Lines
M. Peimbert, A. Peimbert, C. Esteban +5
Based on O II recombination lines we present a new calibration (called O II[RL]) of Pagel's O23 indicator to determine the O/H abundance ratio in extragalactic H II regions and emi…
Temperature Variations and Chemical Abundances in Planetary Nebulae
Manuel Peimbert, Antonio Peimbert
In this review we present a brief discussion on the observational evidence in favor of the presence of temperature variations, and conclude that many planetary nebulae show spatial…
Faint emission lines in the Galactic H II regions M16, M20 and NGC 3603
J. Garcia-Rojas, C. Esteban, M. Peimbert +4
We present deep echelle spectrophotometry of the Galactic {\hii} regions M16, M20 and NGC 3603. The data have been taken with the Very Large Telescope Ultraviolet-Visual Echelle Sp…
