Macroscopic properties of neutron stars including deformation

We used the equations of state of dense nuclear matter to construct the macroscopic properties of neutron stars and test them using available observational results. The Dirac-Brueckner-Hartree-Fock mean field calculations approximated by their parameterized form are the basis of our calculations. We calculated the central pressure and density and correspondingly the possible radius and mass both with and without allowance for hyperons first, and compared these results with recent astronomical observations, and, finally, we included effect of deformation and rotation.
