Gravitational Fragmentation of Extremely Metal-poor Circumstellar Discs

By Kunihiro Shima and Takuya Hosokawa
We study the gravitational fragmentation of circumstellar discs accreting extremely metal-poor (Z \leq 10^{-3} Zsun) gas, performing a suite of three-dimensional hydrodynamic simulations using the adaptive mesh refinement code Enzo. We systematically follow the long-term evolution for 2000 years after the first protostar's birth, for the cases of $Z =... Show more
