Population III star formation in the presence of turbulence, magnetic fields and ionizing radiation feedback

Understand

Turbulence, magnetic fields and radiation feedback are key components that shape the formation of stars, especially in the metal-free environments at high redshifts where Population III stars form.

• Yet no 3D numerical simulations exist that simultaneously take all of these into account.
• We present the first suite of radiation-magnetohydrodynamics (RMHD) simulations of Population III star formation using the adaptive mesh refinement (AMR) code FLASH as part of the POPSICLE project.
• We include both turbulent magnetic fields and ionizing radiation feedback coupled to primordial chemistry, and resolve the collapse of primordial clouds down to few au.
