非均匀小行星附近的动力学环境值得研究，因为许多小天体具有不同的内部结构。本文研究了异质丝川的暂时共振效应。零功率曲线将空间划分为四个区域。试验粒子在区域I和区域III经历轨道能量增强，而在区域II和区域IV经历轨道能量衰减。此外，非均质和均质情况下的零功率曲线也存在差异。非均匀丝川引力场的引力幂绝对值比均匀丝川引力场的引力幂绝对值显著。这意味着粒子在非均匀体附近受到较强的能量变化。在区域II和区域III中进行的数值模拟验证了差异。因此，邻近的喷出物更容易从异质的Itokawa中逃逸，这可能导致表面上物质的更频繁的交换。这些结果使我们更好地理解尘埃在非均匀物体附近的运动。此外，非均匀体附近的暂时共振的性能可以作为一个指导原则，探测器轨道的小行星具有不同的内部结构。
Dynamic environment near heterogeneous asteroids is worth studying since many small bodies have varied internal structures. In this paper, we investigated the effect of temporary resonance with the heterogeneous Itokawa. Zero-power curves divide the space into four regions. The test particle experiences orbital energy-enhancing in the Region I and Region III, but receding in the Region II and Region IV. Moreover, there are differences in zero-power curves between the heterogeneous and homogeneous cases. The absolute values of gravity power in the gravitational field of heterogeneous Itokawa are more significant than those of the homogeneous one. It means the particle suffers from stronger energy change near the heterogeneous body. Numerical simulations conducted in Region II and Region III verify the difference. Thus, vicinal ejecta is easier to run away from a heterogeneous Itokawa, which may lead to a more frequent exchange of materials on the surface. These results give a better understanding of dust’s motion near a heterogeneous body. Moreover, the performance of temporary resonance near a heterogeneous body might serve as a guiding principle for probe orbiting an asteroid with a varied internal structure.
