In a new theory called Dynamic Theory of Gravity, the gravitational potential is is derived from gauge relations and has a different form than the classical Newtonian potential. In the same theory an analytical expression for the pressure is derived from the equation of the hydronamic equilibrium which is solved for a star of constant density and the results are compared with those of Newtonian gravity. Changes then in the central pressure and radius are also calculated and finally a redshift calculation is performed so that the dynamic gravity effects if any might be shown to be of some detectabe magnitude.
