Carbon, nitrogen and oxygen abundance gradients in M101 and M31
C. Esteban, F. Bresolin, J. García-Rojas +1
We present deep spectrophotometry of 18 HII regions in the nearby massive spiral galaxies M101 and M31. We have obtained direct determinations of electron temperature in all the ne…
Chemical abundances and temperature structure of H II regions
G. Domínguez-Guzmán, M. Rodríguez, C. Esteban +1
We use a sample of 37 H II regions with high quality spectra to study the behavior of the relative abundances of several elements as a function of metallicity. The sample includes…
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…
