The Equation of State of
Quasi-Particle Model at
Finite Chemical potential and Quark Star, H. S. Zong, Department
of
Physics, Nanjing University, China − In this paper, we
employ the equation
of state (EOS) of the quasi-particle model which incorporates the
effect of
vacuum negative pressure to study the properties of quark star. In our model the EOS has
the correct behavior
required by QCD in the small and large μ limit. We employ this EOS to
calculate the mass-radii
relation and mass-energy density relation of quark star. Our results are found to
be consistent with
the most recent astronomical observations.
