Strange stars admixed with mirror dark matter: confronting observations of XTE J1814-338
Shu-Hua Yang, Chun-Mei Pi, Fridolin Weber
In this paper, we explore a novel framework for explaining the mass and radius relationships of observed neutron stars by considering strange stars (SSs) admixed with mirror dark m…
Color-flavor locked strange stars admixed with mirror dark matter and the observations of compact stars
S. -H. Yang, C. -M. Pi
We investigate the structure and the tidal deformability of the color-flavor locked strange stars admixed with mirror dark matter. Assuming the stars in the GW170817 event have a m…
Confronting strange stars with compact-star observations and new physics
Shu-Hua Yang, Chun-Mei Pi, Xiao-Ping Zheng +1
Strange stars ought to exist in the universe according to the strange quark matter hypothesis, which states that matter made of roughly equal numbers of up, down, and strange quark…
Strange stars with a mirror-dark-matter core confronting with the observations of compact stars
Shu-Hua Yang, Chun-Mei Pi, Xiao-Ping Zheng
We investigate the structure and the tidal deformability of strange stars (SSs) with a mirror-dark-matter (MDM) core for the standard MIT bag model. We find that to explain the obs…
Constraints from compact star observations on non-Newtonian gravity in strange stars based on a density dependent quark mass model
Shu-Hua Yang, Chun-Mei Pi, Xiao-Ping Zheng +1
Using a density dependent quark mass (QMDD) model for strange quark matter, we investigate the effects of non-Newtonian gravity on the properties of strange stars and constrain the…
Non-Newtonian gravity in strange quark stars and constraints from the observations of PSR J0740+6620 and GW170817
Shu-Hua Yang, Chun-Mei PI, Xiao-Ping Zheng +1
We investigate the effects of non-Newtonian gravity on the properties of strange quark stars (QSs) and constrain the parameters of the standard MIT bag model used to describe stran…
R-mode instability of strange stars and observations of neutron stars in LMXBs
Chun-Mei PI, Shu-Hua Yang, Xiao-Ping Zheng
Using a realistic equation of state (EOS) of strange quark matter, namely, the modified bag model, and considering the constraints to the parameters of EOS by the observational mas…
Rapid cooling of neutron star in Cassiopeia A and r-mode damping in the core
Shu-Hua Yang, Chun-Mei Pi, Xiao-Ping Zheng
We proposed alternative explanation to the rapid cooling of neutron star in Cas A. It is suggested that the star is experiencing the recovery period following the r-mode heating pr…
The termination shock of a magnetar wind: a possible origin of gamma-ray burst X-ray afterglow emission
Z. Mao, Yun-Wei Yu, Z. G. Dai +2
Context: Swift observations suggest that the X-ray afterglow emission of some gamma-ray bursts (GRB) may have internal origins, and the conventional external shock (ES) cannot be t…
Effects of rotochemical heating on the thermal evolution of superfluid neutron stars
Chun-Mei Pi
The authors take the rotochemical heating effect into account, which may make the cooling scenario different. Their model is consistent with the observation data.
The extension of radiative viscosity to superfluid matter
Chun-Mei Pi, Shu-Hua Yang, Xiao-Ping Zheng
The radiative viscosity of superfluid matter is studied, and it is found that to the lowest order of the ratio of radiative viscosity to bulk viscosity is the same as…
Radiative viscosity of neutron stars
Shu-Hua Yang, Xiao-Ping Zheng, Chun-Mei Pi
We study non-linear effects of radiative viscosity of matter in neutron stars for both direct Urca process and modified Urca process, and find that non-linear effects will de…
The role of -mode damping in the thermal evolution of neutron stars
Shu-Hua Yang, Xiao-Ping Zheng, Chun-Mei Pi +1
The thermal evolution of neutron stars (NSs) is investigated by coupling with the evolution of -mode instability that is described by a second order model.The heating e…
