Evolution of star-forming dwarf galaxies: characterizing the star formation scenarios.

MARTIN-MANJON M.L., MOLLA M., DIAZ A.I. and TERLEVICH R.

Abstract (from CDS):

We use the self-consistent model technique developed by Martìn-Manjón et al. that combines the chemical evolution with stellar population synthesis and photoionization codes, to study the star formation scenarios capable of reproducing the observed properties of star-forming galaxies.

The comparison of our model results with a data base of H II galaxies shows that the observed spectra and colours of the present burst and the older underlying population are reproduced by models in a bursting scenario with star formation efficiency involving close to 20 per cent of the total mass of gas, and interburst times longer than 100 Myr, and more probably around 1 Gyr. Other modes like gasping and continuous star formation are not favoured.
