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…
Equation of motion for relativistic compact binaries with the strong field point particle limit : the second and half post-Newtonian order
Yousuke Itoh, Toshifumi Futamase, Hideki Asada
We study the equation of motion appropriate to an inspiralling binary star system whose constituent stars have strong internal gravity. We use the post-Newtonian approximation with…
