摘      要：The influence of a third-body s orbital elements on the second-body s motion in a hierarchical triple system is a crucial problem in *** prolonged evaluation studies have focused on a distant zero-inclined *** study presents a new perspective on second-body motion equations that addresses a perturbing-body in an elliptic orbit derived with consideration of the axial-tilt(obliquity)of the *** proposed model is compared by the dual-averaged method and the N-body problem *** validation,a generalized threebody model is derived to investigate the effects of the third-body s orbital elements on secondary-body motion *** proposed model considers short-time oscillations that affect secular evaluation and applies to exoplanets with all the primary and third body eccentricities,inclinations,and mass *** is shown that the obliquity of the primary(or third-body s inclination)must be considered for precise long-term assessment,even in highly-hierarchical systems.
