从希尔稳定性的角度讨论了双星系统或行星系统与在倾斜于该系统的抛物轨道上运动的第三体的动力学相互作用。这种情况出现在双星的破坏和交换，在太阳系外行星系统的破坏，交换和捕获。结果表明，随着第三体倾角的增大，希尔稳定区减小。这使得组成质量的交换或破坏更有可能增加双星的离心率。稳定性标准用于确定目前已知的太阳系外行星系统可能的破坏和捕获距离。
The dynamical interaction of a binary or planetary system and a third body moving on a parabolic orbit inclined to the system is discussed in terms of Hill stability for the full three-body problem. The situation arises in binary star disruption and exchange, in extrasolar planetary system disruption, exchange and capture. It is found that increasing the inclination of the third body decreases the Hill regions of stability. This makes exchange or disruption of the component masses more likely as does increasing the eccentricity of the binary. The stability criteria are applied to determine possible disruption and capture distances for currently known extrasolar planetary systems.
