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…
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…
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…
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…
Thermal x-ray studies of neutron stars and the equation of state
Zhiqiang Miao, Liqiang Qi, Juan Zhang +2
The understanding of neutron star equation of state hinges on a comprehensive analysis of multi-messenger, multi-wavelength data. The recent scrutiny of PSR J0030+0451 data by NICE…
On the spin period distribution of millisecond pulsars
Xiao-Jin Liu, Zhi-Qiang You, Zu-Cheng Chen +3
Spin period distribution provides important clues to understand the formation of millisecond pulsars (MSPs). To uncover the intrinsic period distribution, we analyze three samples…
Two-flavor color superconducting quark stars may not exist
Wen-Li Yuan, Ang Li
Large uncertainties in the determinations of the equation of state of dense stellar matter allow the intriguing possibility that the bulk quark matter in beta equilibrium might be…
Internal Plateau in Short GRBs and Quark Stars
A. Li
I summarize our recent calculations on quark stars (QSs), for the purpose of explaining some short gamma-ray bursts characterized by internal plateau in their early X-ray afterglow…
