High resolution version of The first stars: formation of binaries and small multiple systems

The following are movies of the simulation presented in the paper. Watch them to view the formation of a small multiple system of Pop III stars from a disk of primordial gas.

The following shows the evolution of the entire 140 kpc (comoving) cosmological box. Also shown is the central 20 kpc (comoving), in which we can see the assembly of the minihalo hosting the Pop III stars.
