Properties of the ionized gas in HH202. I: Results from integral field spectroscopy with PMAS
A. Mesa-Delgado, L. López-Martín, C. Esteban +2
We present results from integral field spectroscopy with the Potsdam multi-Aperture Spectrograph of the head of the Herbig-Haro object HH 202 with a spatial sampling of 1"x1". We h…
M1-78: a nitrogen-rich Galactic compact HII region beyond the Perseus arm
N. L. Martin-Hernandez, C. Esteban, A. Mesa-Delgado +2
There is considerable controversy surrounding the nature of M1-78, a compact nebula located beyond the Perseus arm. It was first classified as a planetary nebula and is nowadays ge…
Small scale behavior of the physical conditions and the abundance discrepancy in the Orion nebula
Adal Mesa-Delgado, César Esteban, Jorge García-Rojas
We present results of long-slit spectroscopy in several positions of the Orion nebula. Our goal is to study the spatial distribution of a large number of nebular quantities, includ…
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…
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…
