Detectablity of Black Hole Binaries with Gaia: Dependence on Binary Evolution Models
Minori Shikauchi, Ataru Tanikawa, Norita Kawanaka
Astrometric satellite Gaia is expected to observe non-interacting black hole (BH) binaries with luminous companions (LCs) (hereafter BH-LC binaries), a different population from BH…
Compact Object Mergers in Hierarchical Triples from Low-Mass Young Star Clusters
Alessandro Alberto Trani, Sara Rastello, Ugo N. Di Carlo +3
A binary star orbited by an outer companion constitutes a hierarchical triple system. The outer body may excite the eccentricity of the inner binary through the von~Zeipel-Lidov-Ko…
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…
Merger rate density of binary black holes through isolated Population I, II, III and extremely metal-poor binary star evolution
Ataru Tanikawa, Takashi Yoshida, Tomoya Kinugawa +4
We investigate the formation of merging binary black holes (BHs) through isolated binary evolution, performing binary population synthesis calculations covering an unprecedentedly…
On the population III binary black hole mergers beyond the pair-instability mass gap
Kotaro Hijikawa, Ataru Tanikawa, Tomoya Kinugawa +2
We perform a binary population synthesis calculation incorporating very massive population (Pop.) III stars up to 1500 , and investigate the nature of binary black hole (B…
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…
