Rational Orbits and Gravitational-Wave Signatures around a Horndeski Black Hole
Wei Gao, Xiaoyan Zhu, Wenbin Lin +1
We study equatorial timelike geodesics and associated gravitational-wave (GW) emission for a static Horndeski black hole with secondary scalar hair, characterized by an effective p…

Gravitational losses for the binary systems induced by the next-to-leading spin-orbit coupling effects
Hao Zhang, Wei Gao, Guansheng He +3
The orbital energy and momentum of the compact binary systems will loss due to gravitational radiation. Based on the mass and mass-current multipole moments of the binary system wi…
