Compact Binary Formation in Open Star Clusters III: Probability of Binary Black Holes Hidden in Gaia Black Hole Binary
Ataru Tanikawa, Long Wang, Michiko S. Fujii +3
The Gaia mission and its follow-up observations have discovered a few candidates of non-interacting single black holes (BHs) and visible stars, Gaia BH1, BH2, and BH3, collectively…
Constraining the binarity of black hole candidates: a proof-of-concept study of Gaia BH1 and Gaia BH2
Toshinori Hayashi, Yasushi Suto, Alessandro A. Trani
Nearly a hundred of binary black holes (BBHs) have been discovered with gravitational-wave signals emitted at their merging events. Thus, it is quite natural to expect that signifi…
Lagrange vs. Lyapunov stability of hierarchical triple systems: dependence on the mutual inclination between inner and outer orbits
Toshinori Hayashi, Alessandro A. Trani, Yasushi Suto
While there have been many studies examining the stability of hierarchical triple systems, the meaning of ``stability'' is somewhat vague and has been interpreted differently in pr…
Dynamical disruption timescales and chaotic behavior of hierarchical triple systems
Toshinori Hayashi, Alessandro A. Trani, Yasushi Suto
We examine the stability of hierarchical triple systems using direct -body simulations without adopting a secular perturbation approximation. We estimate their disruption timesc…
Unveiling the architecture of a pulsar - binary black-hole triple system with pulsar arrival time analysis
Toshinori Hayashi, Yasushi Suto
A large number of binary black holes (BBHs) with longer orbital periods are supposed to exist as progenitors of BBH mergers recently discovered with gravitational wave (GW) detecto…
Radial-velocity variation of a tertiary star orbiting a binary black hole in coplanar and non-coplanar triples: short- and long-term anomalous behavior
Toshinori Hayashi, Yasushi Suto
A number of ongoing surveys are likely to discover star-black hole binaries in our Galaxy in the near future. A fraction of them may be triple systems comprising an inner binary, i…
