Times Cited Count：1 Percentile：48.93(Astronomy & Astrophysics)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] 
-3.5, and derive relations between abundance ratios and explosion properties of Pop III SNe.

The third symposium on Science of Hadrons under Extreme Conditions, organized by the Research Group for Hadron Science, Advanced Science Research Center, was held at Tokai Research Establishment of JAERI on January 29 to 31, 2001. The symposium was devoted for discussions and presentations of research results in wide variety of hadron physics such as nuclear matter, high-energy nuclear reactions, quantum chromodynamics, neutron stars,supernovae, nucleosynthesis as well as finite nuclei to understand various aspects of hadrons under extreme conditions. Twenty two papers on these topics, including a special talk on the present status of JAERI-KEK joint project on high-intentisy proton accelerator, presented at the symposium aroused lively discussions among approximately 40 participants.
