Quakes in Solid Quark Stars
A. Z. Zhou, R. X. Xu, X. J. Wu +2
A starquake mechanism for pulsar glitches is developed in the solid quark star model. It is found that the general glitch natures (i.e., the glitch amplitudes and the time interval…
Surface Electric Field of Bare Strange Stars
Jian Hu, R. X. Xu
The surface electric characteristics of bare strange stars are investigated with the inclusion of boundary effects. The thickness of the electron layer where pairs can be spontaneo…
Pulsar braking index: A test of emission models?
R. X. Xu, G. J. Qiao
Pulsar braking torques due to magnetodipole radiation and to unipolar generator are considered, which results in braking index being less than 3 and could be employed to test the e…
The birth of strange stars and their dynamo-originated magnetic fields
R. X. Xu, F. H. Busse
It is shown that protostrange stars (PSSs) can be convective and that there are two possible scenarios describing their turbulence. Besides the local turbulence on the scale which…
Nature and Nurture: a model for soft gamma-ray repeaters
Bing Zhang, R. X. Xu, G. J. Qiao
During supernova explosions, strange stars with almost bare quark surfaces may be formed. Under certain conditions, these stars could be rapidly spun down by the torque exerted by…
What if pulsars are born as strange stars?
R. X. Xu, Bing Zhang, G. J. Qiao
The possibility and the implications of the idea, that pulsars are born as strange stars, are explored. Strange stars are very likely to have atmospheres with typical mass of $\sim…
An inverse Compton scattering (ICS) model of pulsar emission: III. polarization
R. X. Xu, J. F. Liu, J. L. Han +1
Qiao and his collaborators recently proposed an inverse Compton Scattering (ICS) model to explain radio emission of pulsars. In this paper, we investigate the polarization properti…
PSR 0943+10: a bare strange star?
R. X. Xu, G. J, . Qiao +1
Recent work by Rankin & Deshpande strongly suggests that there exist strong ``micro-storms'' rotating around the magnetic axis of the 1.1s pulsar PSR 0943+10. Such a feature hints…
