The optical/ultraviolet excess of isolated neutron stars in the resonant cyclotron scattering model
《Research in Astronomy and Astrophysics》2011年第12期1371-1376,共6页Hao Tong Ren-Xin Xu Li-Ming Song 
supported by the National Natural Science Foundation of China (NSFC, GrantNos. 10935001 and 10973002);the National Basic Research Program of China (973 Program, Grant No. 2009CB824800);the John Templeton Foundation
X-ray dim isolated neutron stars are peculiar pulsar-like objects, characterized by their Planck-like spectrum. In studying their spectral energy distributions, optical/ultraviolet （UV） excess is a long standing pro...

The plateau of gamma-ray burst:hint for the solidification of quark matter?
《Science China(Physics,Mechanics & Astronomy)》2011年第8期1541-1545,共5页DAI Shi LI LiXin XU RenXin 
supported by the National Natural Science Foundation of China (Grant Nos. 10973002, 10973003 and 10935001);the National Basic Research Program of China (Grant Nos. 2009CB24901, 2009CB824800);the John Templeton Foundation and the National Fund for Fostering Talents of Basic Science (Grant No. J0630311)
The origin of the shallow decay segment in γ-ray bursts' (GRB) early light curves remains a mystery, especially those cases with a long-lived plateau followed by an abrupt falloff. In this paper, we propose to unders...

A new parametric equation of state and quark stars
《Chinese Physics C》2011年第7期616-621,共6页那学森 徐仁新 
Supported by China Scholarship Council, NSFC (10973002, 10935001);National Basic Research Program of China (2009CB824800);the John Templeton Foundation
It is still a matter of debate to understand the equation of state of cold matter with supra-nuclear density in compact stars because of unknown non-perturbative strong interaction between quarks. Nevertheless, it is ...

A note on the discovery of a 2M_⊙ pulsar
《Research in Astronomy and Astrophysics》2011年第6期687-691,共5页Xiao-Yu Lai Ren-Xin Xu 
supported by the National Natural Science Foundation of China (Grant Nos. 10935001 and 10973002);the National Basic Research Program of China (973 program, Grant No. 2009CB824800);the China Postdoctoral Science Foundation and the John Templeton Foundation
It is conventionally thought that the state equation of dense matter softens and thus cannot result in high maximum mass if pulsars are quark stars and that a recently discovered 2M⊙ pulsar （PSR J1614–2230） may ma...

SWIFT J1749.4-2807: A neutron or quark star?
《Research in Astronomy and Astrophysics》2010年第9期815-820,共6页Jun-Wei Yu Ren-Xin Xu 
supported by the National Natural Science Foundation of China (Grant Nos. 10778611 and 10973002);the National Basic Research Program of China(Grant No. 2009CB824800)
We investigate a unique accreting millisecond pulsar with X-ray eclipses, SWIFT J1749.4-2807 （hereafter J1749）, and try to set limits on the binary system by various methods including use of the Roche lobe, the mass...

Supported by NSFC (10778611,10973002);National Basic Research Program of China (2009CB824800) and LCWR (LHXZ200602)
Quarks are proposed to be grouped together to make quark-clusters due to the strong interaction in cold quark matter at a few nuclear densities,because a weakly coupling treatment of the interaction between quarks the...
