Neutron stars in the bumblebee theory of gravity
Peixiang Ji, Zhuhai Li, Lirui Yang +3
Recently, theoretical studies on the bumblebee gravity model, a nonminimally-coupled vector-tensor theory that violates the Lorentz symmetry, have flourished, with a simultaneous i…
Dynamic instability analysis for bumblebee black holes: the odd parity
Zhan-Feng Mai, Rui Xu, Dicong Liang +1
Spherical black-hole (BH) solutions have been found in the bumblebee gravity where a vector field nonminimally couples to the Ricci tensor. We study dynamic (in)stability associate…
Probing the vector charge of Sagittarius A* with pulsar timing
Zexin Hu, Lijing Shao, Rui Xu +2
Timing a pulsar orbiting around Sagittarius A* (Sgr A*) can provide us with a unique opportunity of testing gravity theories. We investigate the detectability of a vector charge ca…
Neutron stars more compact than black holes as a probe of strong-field gravity
Shoulong Li, H. Lü, Yong Gao +3
Probing gravity in its strongest regime is a central goal of modern physics, as the nature of the most compact objects reflects fundamental aspects of Einstein's theory of general…
