Self-consistent -body simulation of Planetesimal-Driven Migration. II. The effect of PDM on planet formation from a planetesimal disk

Tenri Jinno, Takayuki R. Saitoh, Yoko Funato +1

According to the canonical planet formation theory, planets form "in-situ" within a planetesimal disk via runaway and oligarchic growth. This theory, however, cannot naturally acco…

A new approach for predicting the stability of hierarchical triple systems -- I. Coplanar Cases

Ryutaro Iwakura, Yoko Funato, Junichiro Makino

Hierarchical triple systems play a crucial role in various astrophysical contexts, and therefore the understanding of their stability is important. Traditional empirical stability…

Self-consistent -body simulation of Planetesimal-Driven Migration I. The trajectories of single planets in the uniform background

Tenri Jinno, Takayuki R. Saitoh, Yoko Funato +1

Recent exoplanet observations have revealed a diversity of exoplanetary systems, which suggests the ubiquity of radial planetary migration. One powerful known mechanism of planetar…

Particle-Particle Particle-Tree: A Direct-Tree Hybrid Scheme for Collisional N-Body Simulations

Shoichi Oshino, Yoko Funato, Junichiro Makino

In this paper, we present a new hybrid algorithm for the time integration of collisional N-body systems. In this algorithm, gravitational force between two particles is divided int…

Eccentric evolution of SMBH binaries

Masaki Iwasawa, Sangyong An, Tatsushi Matsubayashi +2

In recent numerical simulations \citep{matsubayashi07,lockmann08}, it has been found that the eccentricity of supermassive black hole(SMBH) - intermediate black hole(IMBH) binaries…

The origin of S-stars and a young stellar disk: distribution of debris stars of a sinking star cluster

Michiko Fujii, Masaki Iwasawa, Yoko Funato +1

Within the distance of 1 pc from the Galactic center (GC), more than 100 young massive stars have been found. The massive stars at 0.1-1 pc from the GC are located in one or two di…
