A. Ahmad et al., EXISTENCE OF PERIODIC-ORBITS OF COLLISION IN THE PHOTOGRAVITATIONAL CIRCULAR RESTRICTED PROBLEM OF 3 BODIES IN 3-DIMENSIONAL COORDINATE SYSTEM, Indian Journal of Pure and Applied Mathematics, 25(5), 1994, pp. 559-566
This paper deals with the motion of an infinitesimal mass in the gravi
tational field of the sun and planet taking into account the effect of
radiation pressure of the sun on the planet as well as the infinitesi
mal mass. The existence of periodic orbits of collision in the photogr
avitational circular restricted problem of three bodies in three-dimen
sional co-ordinate system has been studied here. We shall assume that
the third co-ordinate q3 is of the order of mu.
