Scientific paper

The first metal enrichment in the universe was made by supernova explosions of population III stars. The evolution of the early universe is traced by extremely metal-poor (EMP) stars. In this paper, supernova nucleosynthesis is reported and compared with the abundance patterns of the EMP stars. The variations of the EMP stars stem from variations of supernova properties: main-sequence masses, explosion energies, and energy deposition rates. Future detailed studies could constrain the explosion mechanism of gamnma-ray bursts and supernovae.
