SIRIUS Project. IV. The formation history of the Orion Nebula Cluster driven by clump mergers
Michiko S. Fujii, Long Wang, Yutaka Hirai +3
The Orion Nebula Cluster (ONC) is an excellent example for understanding the formation of star clusters. Recent studies have shown that ONC has three distinct age populations and a…
Neutron star mergers as the astrophysical site of the r-process in the Milky Way and its satellite galaxies
Shinya Wanajo, Yutaka Hirai, Nikos Prantzos
Recent progress of nucleosynthesis work as well as the discovery of a kilonova associated with the gravitational-wave source GW170817 indicates that neutron star mergers (NSM) can…
SIRIUS Project. III. Star-by-star simulations of star cluster formation using a direct N-body integrator with stellar feedback
Michiko S. Fujii, Takayuki R. Saitoh, Yutaka Hirai +1
One of the computational challenges of cluster formation simulations is resolving individual stars and simulating massive clusters with masses of more than without…
-process enhancements of Gaia-Enceladus in GALAH DR3
Tadafumi Matsuno, Yutaka Hirai, Yuta Tarumi +3
The dominant site of production of -process elements remains unclear despite recent observations of a neutron star merger. Observational constraints on the properties of the sit…
