Introduction of ShortRange Effects in the OppenheimerVolkoff Equation
Abstract
Motivated by the recent questioning of the inversesquare law, the influence of shortrange effects on the structure of a neutron star is presently investigated. This is analyzed by introducing an additional scalar (vector) massive field into the OppenheimerVolkoff formalism, which gives rise to a new attractive (repulsive) effect between the neutrons. This can be viewed as a simple modification of the equation of state. When phenomenologically acceptable parameters are used, the resulting effects on the star structure are unobservable.
