Abstract

By resolving Tolman-Oppenheimer-Volkoff equation based on a temperature, de
nsity, and isospin dependent nuclear equation of state of nuclear matter, w
e obtained the mass of neutron star as a function of central density, and t
he radius of neutron star was also investigated. It is found that both the
maximum mass and the radius of neutron star strongly depend on the incompre
ssibility, symmetry energy strength coefficient, and effective mass of nucl
eon. With the increment of the incompressibility and symmetry energy streng
th coefficient and the decrement of the nucleon effective mass, the maximum
mass of nentron star increases. Meanwhile, the nuclear equation of state w
ith large incompressibility, symmetry energy strength coefficient and nucle
on effective mass results in relatively large neutron radius. These results
imply that one can get some information about the nuclear equation of stat
e by investigating the macroscopical variables of neutron stars such as mas
s and radius etc. The relationship of the mass and radius of neutron star i
s also investigated.
