Distribution of supernova properties in the early universe

Tominaga, Nozomu*; Iwamoto, Nobuyuki ; Nomoto, Kenichi*

The first metal enrichment in the universe was made by a supernova (SN) explosion of a population (Pop) III star. Chemical abundance in the early universe is recorded in abundance patterns of extremely metal-poor (EMP) stars. Increasing number of the EMP stars is now being discovered and allows us to statistically constrain explosion properties of Pop III SNe. We present Pop III SN models that reproduce well individual abundance patterns of 48 most metal-poor stars with [Fe/H] $_sim^{<}$ -3.5, and derive relations between abundance ratios and explosion properties of Pop III SNe.
