Journal ArticleDOI
Using Strong Lines to Estimate Abundances in Extragalactic H II Regions and Starburst Galaxies
Lisa J. Kewley,Michael A. Dopita +1 more
TL;DR: In this article, the authors used a combination of stellar population synthesis and photoionization models to develop a set of ionization parameter and abundance diagnostics based only on the use of the strong optical emission lines.
Journal ArticleDOI
The Evolution of Rotating Stars
André Maeder and,Georges Meynet +1 more
TL;DR: In this paper, the main physical effects to be considered in the building of evolutionary models of rotating stars on the Upper Main Sequence (MS) were reviewed, and the internal rotation of the stars was discussed.
Journal ArticleDOI

John Moustakas,Robert C. Kennicutt,Robert C. Kennicutt,Christy Tremonti,Daniel A. Dale,J. D. T. Smith,Daniela Calzetti +6 more
TL;DR: In this article, an intermediate-resolution optical spectrophotometry of 65 galaxies obtained in support of the Spitzer Infrared Nearby Galaxies Survey (SINGS) is presented.

Stellar evolution with rotation VIII: Models at Z = 10^{-5} and CNO yields for early galactic evolution
Georges Meynet,André Maeder +1 more
TL;DR: In this paper, a grid of star models with and without the effects of axial rotation for stars in the mass range between 2 and 60 M for the metallicity $Z = 10^{-5} was computed up to the end of the carbon burning phase.
