Neutron stars more compact than black holes in quasi-topological gravity: Equilibrium configurations and radial stability
Liang Liang, Zhe Luo, Shoulong Li +1
Within general relativity, black holes are widely regarded as the ultimate benchmark for compactness in the Universe. Recently, however, neutron star models have been constructed i…
Neutron stars more compact than black holes as a probe of strong-field gravity
Shoulong Li, H. Lü, H. Lü +4
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…
Gravitational waveforms from periodic orbits around a novel regular black hole
Huajie Gong, Sheng Long, Xi-Jing Wang +3
We explore potential quantum gravity signatures by studying periodic orbits and their GW emissions around a novel regular black hole (BH) featuring a Minkowski core. Using a ration…
Quantum coherence of continuous variables in the black hole quantum atmosphere
Xiaofang Liu, Cuihong Wen, Jieci Wang
Recently, the concept of quantum atmosphere has been introduced as a potential origin of Hawking quanta. This study investigates the properties of quantum fields by exploring the q…
Polarized image of an equatorial emitting ring around a Konoplya-Zhidenko rotating non-Kerr black hole
Xin Qin, Fen Long, Songbai Chen +1
We investigate the polarized images of an equatorial emitting ring around a Konoplya-Zhidenko rotating non-Kerr black hole, which introduces an additional deformation parameter. Th…
