Context. Models of star formation in the early universe require a detailed understanding of accretion, fragmentation and radiative feedback in metal-free molecular clouds. Different simulations predict different initial mass functions of the first stars, ranging from predominantly low-mass (0.1−10 MU+2609), to massive (10−100 MU+2609), or even supermassive (100−1000 MU+2609). The mass distribution of the first stars should lead to unique chemical imprints on the low-mass second and later...[Show more]
