X-Ray Flares of Gamma-Ray Bursts: Quakes of Solid Quark Stars?
Renxin Xu, Enwei Liang
We propose a star-quake model to understand X-ray flares of both long and short Gamma-ray bursts (GRBs) in a solid quark star regime. Two kinds of central engines for GRBs are avai…
A Polytropic Model of Quark Stars
X. Y. Lai, R. X. Xu
A polytropic quark star model is suggested in order to establish a general framework in which theoretical quark star models could be tested by observations. The key difference betw…
Possible evidence that pulsars are quark stars
Renxin Xu
It is a pity that the real state of matter in pulsar-like stars is still not determined confidently because of the uncertainty about cold matter at supranuclear density, even 40 ye…
AXPs/SGRs: Magnetars or Quark-stars?
Renxin Xu
The magnetar model and a solid quark star model for anomalous X-ray pulsars/soft gamma-ray repeaters (AXPs/SGRs) are discussed. Different manifestations of pulsar-like stars are sp…
What can the braking indices tell us about pulsars' nature?
Y. L. Yue, R. X. Xu, W. W. Zhu
As a result of observational difficulties, braking indices of only six rotation-powered pulsars are obtained with certainty, all of which are remarkably smaller than the value ($n=…
To Constrain the Parameter Space of the ICS Model
X. H. Cui, K. J. Lee, G. J. Qiao +3
The pulse profile of pulsar gives geometric information about pulsar's radiation model. After investigating the pulse profiles of PSR B1642-03 and PSR B0950+08, we calculate the ra…
