The abundance discrepancy in H II regions
C. Esteban, L. Toribio San Cipriano, J. García-Rojas
In this paper we discuss some results concerning the abundance discrepancy problem in the context of H II regions. We discuss the behavior of the abundance discrepancy factor (ADF)…
The chemical composition of Galactic ring nebulae around massive stars
C. Esteban, A. Mesa-Delgado, C. Morisset +1
We present deep spectra of ring nebulae associated with Wolf-Rayet (WR) and O-type stars: NGC 6888, G2.4+1.4, RCW 58, S 308, NGC 7635 and RCW 52. The data have been taken with the…
Carbon and oxygen abundance gradients in NGC300 and M33 from optical recombination lines
L. Toribio San Cipriano, J. García-Rojas, C. Esteban +2
We present deep spectrophotometry of several Hii regions in the nearby low-mass spiral galaxies NGC 300 and M33. The data have been taken with UVES and OSIRIS spectrographs attache…
