Physics motivated models of pulsar X-ray hotspots: off-center dipole configurations
Chun Huang, Alexander Y. Chen
Recently, it was proposed that an off-center dipole magnetic configuration, together with a non-trivial temperature profile, may be the best model to explain the X-ray light curve…
Revealing Dark Matter's Role in Neutron Stars Anisotropy: A Bayesian Approach Using Multi-messenger Observations
Xue-Zhi Liu, Premachand Mahapatra, Chun Huang +3
Dark matter (DM) continues to evade direct detection, but neutron stars (NSs) serve as natural laboratories where even a modest DM component can alter their structure. While many s…
Model-Independent Determination of the Tidal Deformability of a 1.4 Neutron Star from Gravitational-Wave Measurements
Chun Huang
Tidal deformability of a 1.4 neutron star provides a pivotal window into the physics of dense nuclear matter, bridging gravitational-wave(GW), electromagnetic observation…
Constraining first-order phase transition inside neutron stars with application of Bayesian techniques on PSR J0437-4715 NICER data
Chun Huang, Shashwat Sourav
Understanding the existence of exotic matter phases and phase transitions within the core of neutron stars is crucial to advancing our knowledge of cold-dense matter physics. Recen…
The persistent shift in spin-down rate following the largest Crab pulsar glitch rules out external torque variations due to starquakes
Xiao-Ping Zheng, Wei-Hua Wang, Chun Huang +2
It was previously believed that, the long-term persistent increase in the spin-down rate of the Crab pulsar following a glitch is direct evidence of a starquake-induced glitch or a…
Bayesian inference of strangeon matter using the measurements of PSR J0437-4715 and GW190814
Wen-Li Yuan, Chun Huang, Chen Zhang +2
The observations of compact star inspirals from LIGO/Virgo combined with mass and radius measurements from NICER provide a valuable tool to study the highly uncertain equation of s…
