A TFD model for the Electrospheres of Bare Strange Quark Stars
Hai-Chuan Guo, Ren-Xin Xu, Cheng-Min Zhang
We study the layer of electrons on bare strange star surfaces, taking the Dirac exchange-energy into account. Because electrons are fermions, the electron wave function must be of…
PSR B1257+12: a quark star with planets?
Youling Yue, Renxin Xu
A recent observation has shown that PSR B1257+12 could have quite small X-ray emitting area, only about 2000 m, which is more than three orders smaller than the canonical polar…
Quark clusters in quark stars and possible astrophysical implications
Weiwei Zhu, Renxin Xu
A quark-cluster state, rather than the color-super-conductivity state, may appear in matter with low-temperature but high density, since the phase transition of chiral symmetry bro…
High-energy accelerators above pulsar polar caps
R. X. Xu, G. J . Qiao, B. Zhang
Similar to the terrestrial collision accelerators of electron-antielectron, another kind of accelerator is above a positively or negatively charged pulsar polar cap. In the case of…
A strange star model for GRO J1744-28
Ren Xin Xu, G. J. Qiao
A model is suggested for the bursting x-ray pulsar, GRO J1744-28, where the compact object of the pulsar is proposed to be a strange matter star with crusts. It is suggested that t…
