Webb15 nov. 2001 · Abstract. We describe results from a fully self-consistent three-dimensional hydrodynamical simulation of the formation of one of the first stars in the Universe. In current models of structure formation, dark matter initially dominates, and pregalactic objects form because of gravitational instability from small initial density perturbations. Webb3 nov. 2003 · In particular, we discuss the initial conditions for Population III star formation, as given by variants of the cold dark matter cosmology. Numerical simulations have investigated the collapse and the fragmentation of metal-free gas, showing that the first stars were predominantly very massive. tbnk test https://hkinsam.com

Young star clusters are ideal laboratories to gauge stellar theory, because they are believed to be ensembles of co-eval stars with identical initial chemical compositions. However, r... WebbThe initial mass function (IMF) is an important product of the star formation process (see the recent review by Lee et al., 2024).
