Black Hole Cold Brew: Fermi Degeneracy Pressure
Wei-Xiang Feng, Hai-Bo Yu, Yi-Ming Zhong
We investigate the dynamical instability of a self-gravitating thermal system in the quantum regime, where Fermi degeneracy pressure becomes significant. Using a truncated Fermi-Di…
Gravothermal Phase Transition, Black Holes and Space Dimensionality
Wei-Xiang Feng
In the framework of gravothermal evolution of an ideal monatomic fluid, I examine the dynamical instability of the fluid sphere in (+1) dimensions by exploiting Chandrasekhar's…
On the Dynamical Instability of Monatomic Fluid Spheres in (N+1)-Dimensional Spacetime
Wei-Xiang Feng
In this note, I derive the Chandrasekhar instability of a fluid sphere in (+1)-dimensional Schwarzschild-Tangherlini spacetime and take the homogeneous (uniform energy density)…
The Buchdahl Stability Bound in Eddington-inspired Born-Infeld Gravity
Wei-Xiang Feng, Chao-Qiang Geng, Ling-Wei Luo
We give the Buchdahl stability bound in Eddington-inspired Born-Infeld (EiBI) gravity. We show that this bound depends on an energy condition controlled by the model parameter .…
Equation of State of Neutron Stars with Junction Conditions in the Starobinsky Model
Wei-Xiang Feng, Chao-Qiang Geng, W. F. Kao +1
We study the Starobinsky or model of for neutron stars with the structure equations represented by the coupled differential equations and the \emph{polytropic}…
