In the
present study, we
have obtained a new analytical solution of combined Einstein-Maxwell field equations describing the interior field of a ball
having static spherically symmetric isotropic charged fluid within it.
The charge and electric field intensity are zero at the center and
monotonically increasing towards the boundary of the fluid ball. Besides these, adiabatic index is also
increasing towards the boundary and becomes infinite on it. All other physical
quantities such as pressure, density, adiabatic speed of sound, charge density,
adiabatic index are monotonically decreasing towards the surface. Causality
condition is obeyed at the center of ball. In the limiting case of vanishingly small charge, the solution
degenerates into Schwarzchild uniform density solution for electrically
neutral fluid. The solution joins smoothly to the Reissner-Nordstrom solution over the boundary. We have
constructed a neutron star model by assuming
the surface density . The mass of the neutron star comes
with radius
14.574 km.
