Photoionized Herbig-Haro objects in the Orion Nebula through deep high-spectral resolution spectroscopy II: HH204
J. E. Méndez-Delgado, W. J. Henney, C. Esteban +3
We analyze the physical conditions, chemical composition and other properties of the photoionized Herbig-Haro object HH~204 through Very Large Telescope (VLT) echelle spectroscopy…
Photoionized Herbig-Haro objects in the Orion Nebula through deep high-spectral resolution spectroscopy I: HH529II and III
J. E. Méndez-Delgado, C. Esteban, J. García-Rojas +3
We present the analysis of physical conditions, chemical composition and kinematic properties of two bow shocks -HH529 II and HH529 III- of the fully photoionized Herbig-Haro objec…
Carbon and oxygen in HII regions of the Magellanic Clouds: abundance discrepancy and chemical evolution
L. Toribio San Cipriano, G. Domínguez-Guzmán, C. Esteban +5
We present C and O abundances in the Magellanic Clouds derived from deep spectra of HII regions. The data have been taken with the Ultraviolet-Visual Echelle Spectrograph at the 8.…
Carbon and oxygen abundances from recombination lines in low-metallicity star-forming galaxies. Implications for chemical evolution
C. Esteban, J. García-Rojas, L. Carigi +4
We present deep echelle spectrophotometry of the brightest emission-line knots of the star-forming galaxies He 2-10, Mkn 1271, NGC 3125, NGC 5408, POX 4, SDSS J1253-0312, Tol 1457-…
The Trace of the CNO Cycle in the Ring Nebula NGC6888
A. Mesa-Delgado, C. Esteban, J. García-Rojas +3
We present new results on the chemical composition of the Galactic ring nebula NGC6888 surrounding the WN6(h) star WR136. The data are based on deep spectroscopical observations ta…
Deep high spectral resolution spectroscopy and chemical composition of ionized nebulae
C. Esteban, J. Garcia-Rojas, A. Mesa-Delgado +1
High spectral resolution spectroscopy has proved to be very useful for the advancement of chemical abundances studies in photoionized nebulae, such as H II regions and planetary ne…
