Using the modern equations of state derived from microscopic calculations , we have calculated the neutron star structure .
For the neutron star , we have obtained a minimum mass about 0.1 { M _ { \odot } } which is nearly independent of the equation of state , and a maximum mass between 1.47 { M _ { \odot } } and 1.98 { M _ { \odot } } which is strongly dependent on the equation of state .
It is shown that among the equations of state of neutron star matter which we have used , the stiffest one leads to higher maximum mass and radius and lower central density .
It is seen that the given maximum mass for the Reid-93 equation of state shows a good consistency with the accurate observations of radio pulsars .
We have indicated that the thickness of neutron star crust is very small compared to the predicted neutron star radius .
