Secular solutions at triangular equilibrium point in the generalized photogravitational restricted three body problem

Abstract

In this paper we have found secular solutions at the triangular equilibrium point in the generalized photogravitational restricted three body problem. The problem is generalised in the sense that smaller primary is an oblate spheroid and more massive primary as source of radiation. The triangular point has long or short-period retrograde elliptical orbits. The critical mass parameter decreases with the increase in oblateness and radiation pressure.
