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…
Prospects for probing small-scale dark matter models with pulsars around Sagittarius A*
Zexin Hu, Lijing Shao, Fupeng Zhang
Future observations with next-generation large-area radio telescopes are expected to discover radio pulsars (PSRs) closely orbiting around Sagittarius~A* (Sgr~A*), the supermassive…
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…
Quasi-periodic oscillations during magnetar giant flares in the strangeon star model
Hong-Bo Li, Yacheng Kang, Zexin Hu +3
Soft gamma-ray repeaters (SGRs) are widely understood as slowly rotating isolated neutron stars. Their generally large spin-down rates, high magnetic fields, and strong outburst en…
Moment of Inertia for Axisymmetric Neutron Stars in the Standard-Model Extension
Yiming Dong, Zexin Hu, Rui Xu +1
We develop a consistent approach to calculate the moment of inertia (MOI) for axisymmetric neutron stars (NSs) in the Lorentz-violating Standard-Model Extension (SME) framework. To…
Prospects for detecting neutron star-white dwarf mergers with decihertz gravitational-wave observatories
Yacheng Kang, Chang Liu, Jin-Ping Zhu +6
Based on different neutron star-white dwarf (NS-WD) population models, we investigate the prospects of gravitational-wave (GW) detections for NS-WD mergers, with the help of early…
