Modeling the Pan-Spectral Energy Distribution of Starburst Galaxies. II. Control of the H II Region Parameters

Dopita, Michael; Fischera, Joerg; Sutherland, Ralph; Kewley, Lisa; Tuffs, Richard J; Popescu, Cristina C; van Breugel, Wil; Groves, Brent; Leitherer, Claus


We examine, from a theoretical viewpoint, how the physical parameters of H II regions are controlled in both normal galaxies and in starburst environments. These parameters are the H II region luminosity function, the time-dependent size, the covering fraction of molecular clouds, the pressure in the ionized gas, and the ionization parameter. The factors that control them are the initial mass function (IMF) of the exciting stars, the cluster mass function, the metallicity, and the mean pressure...[Show more]
