Kinematics of Subclusters in Star Cluster Complexes: Imprint of their Parental Molecular Clouds
M. S. Fujii
Star cluster complexes such as the Carina Nebula can have formed in turbulent giant molecular clouds. We perform a series of -body simulations starting from subclustering initia…
Gravitational-Wave Emission from Binary Black Holes Formed in Open Clusters
Jun Kumamoto, Michiko S. Fujii, Ataru Tanikawa
In order to investigate the formation rate of binary black holes (BBHs) in stellar clusters with a mass comparable to open clusters, we performed a series of direct -body simula…
Survival Rates of Planets in Open Clusters: the Pleiades, Hyades, and Praesepe clusters
M. S. Fujii, Y. Hori
In clustered environments, stellar encounters can liberate planets from their host stars via close encounters. Although the detection probability of planets suggests that the plane…
PENTACLE: Parallelized Particle-Particle Particle-Tree Code for Planet Formation
Masaki Iwasawa, Shoichi Oshino, Michiko S. Fujii +1
We have newly developed a Parallelized Particle-Particle Particle-tree code for Planet formation, PENTACLE, which is a parallelized hybrid -body integrator executed on a CPU-bas…
Growth of intermediate mass black holes by tidal disruption events in the first star clusters
Yuya Sakurai, Naoki Yoshida, Michiko S. Fujii
We study the stellar dynamics of the first star clusters after intermediate-mass black holes (IMBHs) are formed via runaway stellar collisions. We use the outputs of cosmological s…
The Keplerian three-body encounter I. Insights on the origin of the S-stars and the G-objects in the Galactic center
Alessandro A. Trani, Michiko S. Fujii, Mario Spera
Recent spectroscopic analysis has set an upper limit to the age of the S-stars, the ~30 B-type stars in highly eccentric orbits around the supermassive black hole (SMBH) in the Gal…
Modeling the Milky Way as a Dry Galaxy
Michiko S. Fujii, Jeroen Bédorf, Junichi Baba +1
We construct a model for the Milky Way Galaxy composed of a stellar disc and bulge embedded in a dark-matter halo. All components are modelled as -body systems with up to 8 bill…
