Tracing the Trace Anomaly of Dense Matter inside Neutron Stars
Shiyue Ren, Lap-Ming Lin
The trace anomaly is an important quantity that measures the broken conformal symmetry in neutron star matter. In this work, we present quasi-universal relations that connect…
R-process Nucleosynthesis of Subminimal Neutron Star Explosions
Chun-Ming Yip, Ming-Chung Chu, Shing-Chi Leung +1
We show that a minimum-mass neutron star undergoes delayed explosion after mass removal from its surface. We couple the Newtonian hydrodynamics to a nuclear reaction network of $\s…
I-Love-Q Relations of Fermion-Boson Stars
Kelvin Ka-Ho Lam, Lap-Ming Lin
We investigate the properties of fermion-boson stars (FBSs), which can be viewed as neutron stars with a bosonic dark matter (DM) admixture. A challenge in studying the impact of D…
Revisiting the apparent horizon finding problem with multigrid methods
Hon-Ka Hui, Lap-Ming Lin
Apparent horizon plays an important role in numerical relativity as it provides a tool to characterize the existence and properties of black holes on three-dimensional spatial slic…
