The electron temperatures of SDSS high-metallicity giant extragalactic HII regions.

PILYUGIN L.S., VILCHEZ J.M., CEDRES B. and THUAN T.X.

Abstract (from CDS):

Spectra of high-metallicity [12+log(O/H) ≳ 8.2] Hii regions, where oxygen auroral lines are measurable in both the O+ and O++ zones, have been extracted from the Data Release 6 of the Sloan Digital Sky Survey (SDSS). Our final sample consists of 181 SDSS spectra of Hii regions in galaxies in the redshift range from ∼0.025 to ∼0.17. The t2,O-t3,O diagram is examined. In the SDSS Hii regions, the electron temperature t2,O is found to have a large scatter at a given value of the electron temperature t3,O. The majority of the SDSS Hii regions lie below the t2,O-t3,O relation derived for Hii regions in nearby galaxies, i.e. the positions of the SDSS Hii regions show a systematic shift towards lower t2,O temperatures or/and towards higher t3,O temperatures. The scatter and shift of the SDSS Hii regions in the t2,O-t3,O diagram can be understood if they are composite nebulae excited by two or more ionizing sources of different temperatures.
