A comprehensive study of reported high-metallicity giant H II regions - I. Detailed abundance analysis.
CASTELLANOS M., DIAZ A.I. and TERLEVICH E.
Abstract (from CDS):
For the rest of the regions no line temperature measurements could be made, and the metallicity has been determined by means of both detailed photoionization modelling and the sulphur abundance parameter S23. Only one of these regions shows values of O23 and S23 implying a solar or oversolar metallicity.
According to our analysis, only two of the observed regions can therefore be considered as of high metallicity. These two fit the trends previously found in other high-metallicity Hii regions, i.e., N/O and S/O abundance ratios seem to be higher and lower than solar respectively.
