Abstract: | We can define some adiabatic exponents for neutron star cores. The equality of and 3 leads to an equation of stateE=P ln(K/P) orP=K exp(–E/P). This equation has been solved alongwith equations for hydrostatic equilibrium for different physical conditions at the centre. The parameters of isothermal neutron star cores have been computed by taking surface densityE
a=2×1014 g cm–3. ForP
0=E
0 the maximum mass and radius of neutron star core are 3.25M
and 17.14 km, respectively. |
