Impact of bar resonances in the velocity-space distribution of the solar neighbourhood stars in a self-consistent -body Galactic disc simulation
Tetsuro Asano, Michiko S. Fujii, Junichi Baba +3
The velocity-space distribution of the solar neighbourhood stars shows complex substructures. Most of the previous studies use static potentials to investigate their origins. Inste…
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…
Gravitational Wave Physics and Astronomy in the nascent era
Makoto Arimoto, Hideki Asada, Michael L. Cherry +50
The detections of gravitational waves (GW) by LIGO/Virgo collaborations provide various possibilities to physics and astronomy. We are quite sure that GW observations will develop…
Spin misalignment of black hole binaries from young star clusters: implications for the origin of gravitational waves events
Alessandro Alberto Trani, Ataru Tanikawa, Michiko S. Fujii +2
Recent studies indicate that the progenitors of merging black hole (BH) binaries from young star clusters can undergo a common envelope phase just like isolated binaries. If the st…
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…
Spin distribution of binary black holes formed in open clusters
Jun Kumamoto, Michiko S. Fujii, Alessandro A. Trani +1
We performed direct N-body simulations of open clusters with four different metallicities. To investigate the effective spins of merging binary black holes (BBHs) originated from t…
Impact of initial mass functions on the dynamical channel of gravitational wave sources
Long Wang, Michiko S. Fujii, Ataru Tanikawa
Dynamically formed black hole (BH) binaries (BBHs) are important sources of gravitational waves (GWs). Globular clusters (GCs) provide a major environment to produce such BBHs, but…
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…
