A Study of the Elliptic Restricted Three-Body Problem with Triaxial and Radiating Primaries Surrounded by a Belt

This paper examines the effects of radiation pressure and triaxiality two stars (primaries) surrounded by a belt (circumbinarydisc)onthepositionsandstabilityofathirdbodyofaninfinitesimalmassintheframeworkoftheEllipticrestricted three body problem (ER3BP). We have obtained analytical solutions to triangular equilibrium points their stability also investigated these numerically graphically using radiating binary system (Xi- Bootis Kruger 60). It is observed that positions are affected semi-major axis, eccentricity orbit, triaxiality, primaries potential from belt. The perturbed parameters show destabilizing tendency decreasing range stability. found bestable for 0 < µ µc where critical mass parameter. analysis yielded stable outcome when we consider parameterµ in region Routhonian ratio (0.03852) effect circumbinary disc dominant. radition factors inducing instability even within this range.
