Detecting Lorentz-violation induced by a tensor field with S-star's motion around Sgr A*
Qi Qi, Yu Sang, Xiao-Mei Kuang
Testing Lorentz symmetry in strong gravitational fields provides a unique probe of extensions to standard model. The orbiting motions of the S-stars around the supermassive black h…
Probing a Lorentz-violating parameter from orbital precession of the S2 star around the galactic centre supermassive black hole
Qi Qi, Yu Sang, Xiao-Mei Kuang
Testing Lorentz symmetry in strong gravitational fields provides a promising probe of extensions to general relativity. The supermassive black hole Sgr~A* and the orbit of the S-st…
Timelike bound orbits and pericenter precession around black hole with conformally coupled scalar hair
Qi Qi, Xiao-Mei Kuang, Yong-Zhuang Li +1
We investigate the geodesic motions of timelike particles around a static hairy black hole with conformally coupled scalar field. We mainly focus on the effects of the scalar charg…
Precessing and periodic timelike orbits and their potential applications in Einsteinian cubic gravity
Yong-Zhuang Li, Xiao-Mei Kuang
Einsteinian cubic gravity (ECG) is the most general theory up to cubic order in curvature, which have the same graviton spectrum as the Einstein theory. In this paper, we investiga…
