The collapse and fragmentation of filamentary primordial gas clouds are explored using onedimensional and two-dimensional hydrodynamical simulations coupled with the nonequilibrium processes of hydrogen molecule formation. The cloud evolution is computed from the initial central density nc = 10 − 10 cm. The simulations show that depending upon the initial density, there are two occasions for the fragmentation of primordial filaments. If a filament has relatively low initial density such as nc… CONTINUE READING
