A long-lived remnant neutron star after GW170817 inferred from its associated kilonova

Yun-Wei Yu, Liang-Duan Liu, Zi-Gao Dai

The successful joint observation of the gravitational wave event GW170817 and its multi-wavelength electromagnetic counterparts first enables human to witness a definite merger eve…

Merging Strangeon Stars

X. Y. Lai, Y. W. Yu, E. P. Zhou +2

The state of supranuclear matter in compact star remains puzzling, and it is argued that pulsars could be strangeon stars. What if binary strangeon stars merge? This kind of merger…

From hadrons to quarks in neutron stars: a review

Gordon Baym, Tetsuo Hatsuda, Toru Kojo +3

We review the equation of state of matter in neutron stars from the solid crust through the liquid nuclear matter interior to the quark regime at higher densities. We focus in deta…

Net reaction rate and neutrino emissivity for the Urca process in departure from chemical equilibrium

Wei-Hua Wang, Xi Huang, Xiao-Ping Zheng

We discuss the effect of compression on Urca shells in the ocean and crust of accreting neutron stars, especially in superbursting sources. We find that Urca shells may be deviated…

A statistical study of super-luminous supernovae in the magnetar engine model and implications for their connection with gamma-ray bursts and hypernovae

Yun-Wei Yu, Jin-Ping Zhu, Shao-Ze Li +2

By fitting the bolometric light curves of 31 super-luminous supernovae (SLSNe) with the magnetar engine model, we derive the ejecta masses and magnetar parameters for these SLSNe.…

A possible origin of the Galactic Center magnetar SGR 1745-2900

Quan Cheng, Shuang-Nan Zhang, Xiao-Ping Zheng

Since a large population of massive O/B stars and putative neutron stars (NSs) located in the vicinity of the Galactic center (GC), intermediate-mass X-ray binaries (IMXBs) constit…

Stochastic gravitational wave background from newly born massive magnetars: The role of a dense matter equation of state

Quan Cheng, Shuang-Nan Zhang, Xiao-Ping Zheng

Newly born massive magnetars are generally considered to be produced by binary neutron star (NS) mergers, which could give rise to short gamma-ray bursts (SGRBs). The strong magnet…

Radio Emission from Pulsar Wind Nebulae without Surrounding Supernova Ejecta: Application to FRB 121102

Z. G. Dai, J. S. Wang, Y. W. Yu

In this paper, we propose a new scenario in which a rapidly-rotating strongly-magnetized pulsar without any surrounding supernova ejecta produces fast radio bursts (FRBs) repeatedl…

Modeling the High-energy Emission from the Gamma-ray Binary 1FGL J1018.6-5856

A. M. Chen, C. W. Ng, J. Takata +1

1FGL J1018.6-5856 is a high mass gamma-ray binary containing a compact object orbiting around a massive star with a period of 16.544 d. If the compact object is a pulsar, non-therm…

Constraining the age of a magnetar possibly associated with FRB 121102

Xiao-Feng Cao, Yun-Wei Yu, Zi-Gao Dai

The similarity of the host galaxy of FRB 121102 with those of long gamma-ray bursts and Type I super-luminous supernovae suggests that this FRB could be associated with a young mag…
