Feature of Motion Around D-stars

The motion of test particles around D-stars is investigated by Hamilton-Jacobi method. There may exist bound orbits under certain conditions. The trajector with periastrons at large r are Keplerian in form, except for the periastron shift. The trajectory with periastrons at small r, differ markedly from Keplerian orbits. The radius of the most tightly bound is found.
