Where do the Progenitors of Millisecond Pulsars come from?
Ali Taani, Chengmin Zhang, Mashhoor Al-Wardat +1
Observations of a large population of Millisecond Pulsars (MSPs) show a wide divergence in the orbital periods (from approximately hours to a few months). In the standard view, Low…
Could bright gamma-ray burst optical transients have been recorded historically?
Richard G. Strom, Fuyuan Zhao, Chengmin Zhang
The brightest optical flash from a gamma-ray burst (GRB) was, briefly, a naked-eye object. Several other GRBs have produced optical transients only slightly fainter. We argue that,…
A Systematic Study on Energy Dependence of Quasi-Periodic Oscillation Frequency in GRS 1915+105
Shu-Ping Yan, Jin-Lu Qu, Guo-Qiang Ding +6
Systematically studying all the RXTE/PCA observations for GRS 1915+105 before November 2010, we have discovered three additional patterns in the relation between Quasi-Periodic Osc…
A model for upper kHz QPO coherence of accreting neutron star
J. Wang, C. M. Zhang, Y. H. Zhao +3
{We investigate the coherence of the twin kilohertz quasi-periodic oscillations (kHz QPOs) in the low-mass X-ray binary (LMXB) theoretically. The profile of upper kHz QPO, interpre…
The Different Nature in Seyfert 2 Galaxies With and Without Hidden Broad-Line Regions
Yu-Zhong Wu, En-Peng Zhang, Yan-Chun Liang +2
We compile a large sample of 120 Seyfert 2 galaxies (Sy2s) which contains 49 hidden broad-line region (HBLR) Sy2s and 71 non-HBLR Sy2s. From the difference in the power sources bet…
Testing the Accretion-induced Field-decay and Spin-up Model for Recycled Pulsars
Jing Wang, Cheng-min Zhang, H. -K. Chang
Millisecond radio pulsars have long been proposed to form from a spin-up recycling process in a binary system. In this paper we demonstrate that the accretion-induced field-decay a…
