Multiwavelength Analysis of PSR J0437-4715 with Pulse Profile Modeling
Liqiang Qi, Juan Zhang, Weiwei Xu +6
We present a multi-wavelength analysis of the nearby millisecond pulsar PSR J0437--4715, combining Hubble Space Telescope (HST) far-ultraviolet, ROSAT soft X-ray, and XMM-Newton X-…
A Microphysical Probe of Neutron Star Interiors: Constraining the Equation of State with Glitch Dynamics
Zhonghao Tu, Ang Li
Glitches in neutron stars originate from the sudden transfer of angular momentum between superfluid components and the observable crust. By modeling this glitch dynamics--including…
Unified QMF equation of state for neutron star matter: Static and dynamic properties
Zhonghao Tu, Xiangdong Sun, Shuochong Han +2
We construct a set of unified equations of state based on the quark mean field (QMF) model, calibrated to different values of nuclear symmetry energy slope at the saturation densit…
Timing results of 22 years for PSR J0922+0638
Peng Liu, Mingyang Wang, Jianping Yuan +4
We conducted a timing analysis of PSR J0922+0638 (B0919+06) using data from the Nanshan 26 m radio telescope and the MeerKAT telescope, spanning from January 2001 to March 2023. Du…
Delayed Thermal Relaxation of Rapidly Cooling Neutron Stars: Nucleon Superfluidity and Non-nucleon Particles
Zhonghao Tu, Ang Li
The thermal relaxation time of neutron stars, typically defined by a sudden drop in surface temperature, is usually on the order of 10 to 100 years. In this study, we investigate n…
Exploring nuclear force with pulsar glitch observation
Zhong-Hao Tu, Ang Li
We connect nuclear forces to one of the most notable irregular behaviors observed in pulsars, already detected in approximately 6\% known pulsars, with increasingly accurate data e…
