Exact Toda Black Holes of Rank-2 Lie Groups
H. Lu, Peng-Yu Wu, Ze-Hua Wu +1
We consider Einstein gravity coupled to two Maxwell fields and one dilatonic scalar, and construct spherically-symmetric and static black holes that are charged under both Maxwell…
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…
Full spectrum of Love numbers of Reissner-Nordstrom black hole in D-dimensions
Minghao Xia, Liang Ma, Yi Pang +1
We present a comprehensive analysis of the full spectrum of tidal Love numbers for Reissner-Nordström (RN) black holes in general spacetime dimensions. By perturbing the Einstein-…
The Upper Bound of Event Horizon Formation Time in Generalized Oppenheimer-Snyder Collapse
Zhi-Chao Li, H. Khodabakhshi, H. Lu
We prove that, in the framework of the Oppenheimer-Snyder collapse, the Schwarzschild exterior maximizes the event horizon formation time among all…
Quadratic Curvature Correction to 5D Myers-Perry Metric
Liang Ma, H. Lu
We consider quadratic curvature perturbation to the Myers-Perry black hole in five dimensions at the linear level in the coupling constant. The solution can then be solved order by…
Black Hole Thermodynamics without Black Hole Solutions
Meng-Nan Yang, Guan-Yi Lu, H. Lu
We consider the string-theory inspired Einstein-Maxwell-Maxwell-dilaton theory (EMMD) and show that we can derive the complete set of thermodynamic quantities of charged black hole…
