论文摘要
我们从数值上研究了小行星的伸长率如何控制其表面对远距离的行星遭遇的潮汐效应的敏感性。我们通过考虑形状伸长以及自旋时期和轨道条件来分析表面斜率及其变化。更细长的小行星倾向于具有较高的斜率变化,而可能没有这种变化的总面积的单调增加
We numerically investigate how an asteroid's elongation controls the sensitivity of its surface to tidal effects during a distant planetary encounter beyond the Roche limit. We analyze the surface slope and its variation by considering the shape elongation, as well as the spin period and orbital conditions. A more elongated asteroid tends to have a higher slope variation, while there may not be a monotonic increase of the total area having such a variation
