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 NICER introduces complexities, unveiling a tension with another X-ray observation of the central compact object in HESS J1731-347, specifically concerning the mass-radius constraint of low-mass neutron stars. This...
Pulsars are fast-spinning neutron stars widely spread in our Milky Way. We are using the FAST to carry out the FAST Galactic Plane Pulsar Snapshot (GPPS) survey, and have discovered about 700 pulsars, including more than 160 millisecond pulsars. These discoveries have significantly extended our knowledge of how many weak pulsars exist in our Milky Way. In this talk, we show how we do the...
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 the true ground state of the matter at zero pressure. And quarks will form Cooper pairs very readily since the dominant interaction between quarks is attractive in some channels. As a result, quark matter will...
Type-I X-ray bursts are rapidly brightening phenomena triggered by the nuclear burning of light elements near the surface of accreting neutron stars. Most X-ray bursters behave very irregularly, but some of them show quite regular activity, i.e., constant recurrence time and the similar shape of light curves in the burst sequence. They are called Clocked bursters, which help contain many model...
