  • 海王星可能已經向外遷移到目前的位置,並將許多行星捕獲為共鳴。我們建立了一個半分析模型來模擬海王星的向外遷移,以及共振捕獲的過程。我們的模型可以自然地解釋海王星目前觀察到的半長軸和偏心率。結果表明,3:2和2:1之間的當前共振比主要是由於行星的原始密度分佈,這可能與原始行星的拖曳向內遷移有關。


    Neptune might have migrated outward to the current position, and captured many particles into resonances. We set up a semi-analytic model to simulate the outward migration of Neptune, and the processes of resonant captures. Our model can naturally explain Neptune’s currently observed semi-major axis and eccentricity. The results show that the current resonance ratio between 3:2 and 2:1 is mainly due to the original density distribution of particles, which might be related to drag-induced inward migrations of the original particles.
