Formation of binary millisecond pulsars with relatively high surface dipole magnetic fields
W. Sutantyo, X. -D. Li
We have carried out numerical evolutionary calculations of binary systems to investigate the formation of binary millisecond pulsars (pulsars with white dwarf companions). We apply…
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…
Two-photon annihilation in the pair formation cascades in pulsar polar caps
Bing Zhang, G. J. Qiao
The importance of the photon-photon pair production process () to form pair production cascades in pulsar polar caps is investigated within the framew…
Is Gamma-ray Absorption by Induced Electric Fields Important in the Pulsar Magnetospheres?
Zheng Zheng, Bing Zhang, G. J. Qiao
Although the unified formula for gamma-ray absorption process involving both the magnetic field and a perpendicular electric field derived by Daugherty & Lerche (1975) is correct,…
