Star formation at very low metallicity. II: On the insignificance of metal-line cooling during the early stages of gravitational collapse
ASTROPHYSICAL JOURNAL, no. 2 (2007): 1332-1343
Abstract
We study the influence of low levels of metal enrichment on the cooling and collapse of ionized gas in small protogalactic halos using three-dimensional, smoothed particle hydrodynamics simulations. Our initial conditions represent protogalaxies forming within a "fossil" H ii region, a previously ionized H ii region which has not yet had ...More
