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…
Helium abundances and its radial gradient from the spectra of HII regions and ring nebulae of the Milky Way
J. E. Méndez-Delgado, C. Esteban, J. García-Rojas +2
We determine the radial abundance gradient of helium in the disc of the Galaxy from published spectra of 19 regions and ring nebulae surrounding mass…
Galactic abundance gradients from deep spectra of HII regions
C. Esteban, J. García-Rojas, K. Z. Arellano-Córdova +1
We present some results of an ongoing project devoted to reassess the radial abundance gradients in the disc of the MilkyWay based on deep spectroscopy of Hii regions. The data hav…
