Abstract

When pressure is not negligible in comparison with energy density, the external gravitational field and the motion of particles in it are modified. For spherically symmetric body two effective mass parameters determine the external gravitational field and the motion of particles in it. For distances much larger than the gravitational radius we use the linearized Einstein equations to consider the effects of pressure on test particle motion.
