Statistical Study of 2XMMi-DR3/SDSS-DR8 Cross-correlation Sample
Zhang Yan-Xia, Zhou Xin-Lin, Zhao Yong-Heng +1
Cross-correlating the XMM-Newton 2XMMi-DR3 catalog with the Sloan Digital Sky Survey (SDSS) Data Release 8, we obtain one of the largest X-ray/optical catalogs and explore the dist…
Binary Pulsars in Magnetic Field versus Spin Period Diagram
Pan Yuanyue, Wang Na, Zhang Chengmin
We analyzed 186 binary pulsars (BPSRs) in the magnetic field versus spin period (B-P) diagram, where their relations to the millisecond pulsars (MSPs) can be clearly shown. General…
Observation of flux tube crossings in the solar wind
L. Arnold, G. Li, X. Li +1
Current sheets are ubiquitous in the solar wind.They are a major source of the solar wind MHD turbulence intermittency. They may result from non-linear interactions of the solar wi…
Minimum Accretion Rate for Millisecond Pulsar Formation in Binary System
Yuanyue Pan, Chengmin Zhang, Na Wang
186 binary pulsars are shown in the magnetic field versus spin period (B-P) dia- gram, and their relations to the millisecond pulsars can be clearly seen. We declaim a minimum accr…
Impact of accretion on the statistics of neutron star masses
Z. Cheng, A. Taani, Y. H. Zhao
We have collected the parameter of 38 neutron stars (NSs) in binary systems with spin periods and measured masses. By adopting the Boot-strap method, we reproduced the procedure of…
Constraints on Scalar Spectral Index from Latest Observational Measurements
Hong Li, Jun-Qing Xia, Xinmin Zhang
Recently, the nine-year data release of the Wilkinson Microwave Anisotropy Probe (WMAP9) found that the inflationary models with the scalar spectral index n_s \geq 1 are excluded a…
