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…
Enrichment of Strontium in Dwarf Galaxies
Yutaka Hirai, Shinya Wanajo, Takayuki R. Saitoh
Light trans-iron elements such as Sr serve as the key to understanding the astrophysical sites of heavy elements. Spectroscopic studies of metal-poor stars have revealed large star…
