neutron starquark corestructuremaximum massThe equation of state of deconfined quark matter within the MIT bag model is calculated. This equation of state is used to compute the structure of a neutron star with quark core. It is found that the limiting mass of the neutron star is affected ...
Using as input the neutron charge radius and the dipole radius, constraints on the remaining radii lead to deviations of about 15% from values taken from literature. Some modifications of current values are proposed especially concerning proton radii. Implications of radial quark structure of the ...
Scalar-isovector δ meson in the relativistic mean field theory and the structure of neutron stars with a quark core In the framework of the relativistic mean field theory, we have considered the equation of state of superdense nuclear matter, taking into account an effec... GB Alaverdyan -...
The influence of medium effects on the gross structure of hybrid stars We investigate the influence of medium effects on the structure of hybrid stars, i.e. neutron stars possessing a quark matter core. We found that medium ef... K.,Schertler,and,... - 《Nuclear Physics A》 被引量: 69...

Now, in order to understand the inner structure of a compact stellar object, the most important step is to know the EoS that indicates the physical behavior of fundamental constituents in the analyzing object. Normally, the EoS is defined as p=f(ρ), where p is the pressure and ρ is th...
Generally speaking, conventional neutron stars and non-mainstream quark stars are two types of models to describe the inner structure of pulsars, with the former composed mainly of hadrons and the latter of a peculiar kind of matter whose state equation should be understood in the level of ...
Neutron stars (NSs) provide the astrophysical testing base to obtain the thermodynamic properties of strongly interacting matter at large baryon density and low (or even zero) temperature [1,2,3,4]. From lots of theoretical studies, NSs could be converted to hybrid stars or strange quark stars...
the structure of a nucleus. So far our knowledge about the structure of nuclei is mostly limited to nuclei close to the valley of stability, or nuclei with a deficiency of neutrons, which can be produced in fusion-evaporation reactions with stable beams and stable targets. Future perspectives ...
Massive neutron stars (NS) are expected to possess a quark core. While the hadronic side of the NS equation of state (EOS) can be considered well established, the quark side is quite uncertain. While calculating the EOS of hadronic matter we have used th
