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…
