摘要:
We make use of numerical models to find the critical metallicity for the Pop Ill to Pop II star formation transition. Making use of the Gadget2 SPH code, we successfully reproduce previous results in the literature for a spherically symmetric collapse and then show results from a full 3D treatment. We conclude that dust cooling affects the fragmentation of low metallicity gas clouds and can determine the evolution of the stellar IMF.
