First Stars -- Type Ib Supernovae Connection
Keni'chi Nomoto, Masaomi Tanaka, Yasuomi Kamiya +2
The very peculiar abundance patterns observed in extremely metal-poor (EMP) stars can not be explained by ordinary supernova nucleosynthesis but can be well-reproduced by nucleosyn…

Measurement of the Kerr Spin Parameter by Observation of a Compact Object's Shadow
Kenta Hioki, Kei-ichi Maeda
A black hole casts a shadow as an optical appearance because of its strong gravitational field. We study how to determine the spin parameter and the inclination angle by observing…

Nucleosynthesis of 56Ni in wind-driven Supernova Explosions and Constraints on the Central Engine of Gamma-Ray Bursts
Keiichi Maeda, Nozomu Tominaga
Theoretically expected natures of a supernova driven by a wind/jet are discussed. Approximate analytical formulations are derived to clarify basic physical processes involved in th…
