Gravitational signatures beyond Newton: exploring hierarchical three-body dynamics
Pietro Farina, Mariafelicia De Laurentis, Hideki Asada +2
Hierarchical three-body systems offer a compelling framework to explore the subtle interplay between Newtonian and relativistic gravitational effects in astrophysical environments.…
Correspondence between two gravitational lens equations in a static and spherically symmetric spacetime
Ryuya Kudo, Hideki Asada
Virbhadra and Ellis have proposed a very accurate equation (referred to as VE equation) for the gravitational lens in a static and spherically symmetric spacetime [Phys. Rev. D 62,…
Equivalence between definitions of the gravitational deflection angle of light for a stationary spacetime
Kaisei Takahashi, Ryuya Kudo, Keita Takizawa +1
The Gibbons-Werner-Ono-Ishihara-Asada method for gravitational lensing in a stationary spacetime has been recently reexamined [Huang and Cao, arXiv:2306.04145], in which the gravit…
Triangular solution to the planar elliptic three-body problem in the parametrized post-Newtonian formalism
Yuya Nakamura, Hideki Asada
A triangular solution [Phys. Rev. D 107, 044005 (2023)] has recently been found to the planar circular three-body problem in the parametrized post-Newtonian (PPN) formalism, for wh…
The status of KAGRA underground cryogenic gravitational wave telescope
KAGRA Collaboration, T. Akutsu, M. Ando +146
KAGRA is a 3-km interferometric gravitational wave telescope located in the Kamioka mine in Japan. It is the first km-class gravitational wave telescope constructed underground to…
Can N-body systems generate periodic gravitational waves?
Takamasa Chiba, Tatsunori Imai, Hideki Asada
None of N-body gravitating systems have been considered to emit periodic gravitational waves because of their chaotic orbits when N=3 (or more). We employ a figure-eight orbit as a…
