Population synthesis of HII galaxies.

RAIMANN D., BICA E., STORCHI-BERGMANN T., MELNICK J. and SCHMITT H.

Abstract (from CDS):

We study the stellar population of galaxies with active star formation, determining ages of the stellar components by means of spectral population synthesis of their absorption spectra. The data consist of optical spectra of 185 nearby (z≤0.075) emission-line galaxies. They are mostly Hii galaxies, but we also include some starbursts and Seyfert 2s, for comparison purposes. They were grouped into 19 high signal-to-noise ratio template spectra, according to their continuum distribution, absorption- and emission-line characteristics. The templates were then synthesized with a star cluster spectral base.

The synthesis results indicate that Hii galaxies are typically age-composite stellar systems, presenting important contributions from generations up to as old as 500Myr. We detect a significant contribution of populations with ages older than 1Gyr in two groups of Hii galaxies. The age distributions of stellar populations among starbursts can vary considerably despite similarities in the emission-line spectra. In the case of Seyfert 2 groups we obtain important contributions from the old population, consistent with a bulge.

From the diversity of star formation histories, we conclude that typical Hii galaxies in the local Universe are not systems presently forming their first stellar generation.
