Grouped star formation: converting sink particles to stars in hydrodynamical simulations
K. Y. Liow, S. Rieder, C. L. Dobbs +1
Modelling star formation and resolving individual stars in numerical simulations of molecular clouds and galaxies is highly challenging. Simulations on very small scales can be suf…
The formation and early evolution of embedded star clusters in spiral galaxies
Steven Rieder, Clare Dobbs, Thomas Bending +2
We present Ekster, a new method for simulating star clusters from birth in a live galaxy simulation that combines the smoothed-particle hydrodynamics (SPH) method Phantom with the…
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…
The impact of primordial binary on the dynamical evolution of intermediate massive star clusters
Long Wang, Ataru Tanikawa, Michiko S. Fujii
Observations found that star clusters contain a large fraction of binaries. Tight binaries are an important heating source that influences the long-term dynamical evolution of star…
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…
Preparing the next gravitational million-body simulations: Evolution of single and binary stars in Nbody6++GPU, MOCCA and McLuster
A. W. H. Kamlah, A. Leveque, R. Spurzem +9
We present the implementation of updated stellar evolution recipes in the codes \texttt{Nbody6++GPU, MOCCA} and \texttt{McLuster}. We test them through numerical simulations of sta…
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…
SIRIUS project II: a new tree-direct hybrid code for smoothed particle hydrodynamics/N-body simulations of star clusters
M. S. Fujii, T. R. Saitoh, L. Wang +1
Star clusters form via clustering star formation inside molecular clouds. In order to understand the dynamical evolution of star clusters in their early phase, in which star cluste…
