Non-ideal magnetohydrodynamic simulations of the first star formation: the effect of ambipolar diffusion
Non-ideal magnetohydrodynamic simulations of the first star formation: the effect of ambipolar diffusion
In the present-day universe, magnetic fields play such essential roles in star formation as angular momentum transport and outflow driving, which control circumstellar disc formation/fragmentation and also the star formation efficiency. While only a much weaker field has been believed to exist in the early universe, recent theoretical studies find …
