Abstract

The mass distribution of fragments is an important characteristic that often needs to be defined for forward modelling the interaction of disrupted meteoroids and asteroids with the atmosphere, and which can be inferred to some extent by the distribution of meteorites that fell to the ground. In previous studies, we derived a formula for the mass distribution of fragments of a disrupted body assuming a power law for the distribution in a differential form, and applied this formula to describe the results of many impact experiments modelling fragmentation of asteroids in outer space. The formula represents the cumulative number of fragments as a function of the fragment mass normalized to the total mass, the mass fraction of the largest fragment and the power index, which is the only free parameter adjusted to best fit the analytical distribution to the empirical one. Here, we use the proposed formula to describe the mass distributions of recovered meteorites that fell to the ground after the passage and disruption of thirteen extraterrestrial objects in the atmosphere, as well as the mass distributions of fragments of meteorite samples disrupted in impact experiments. A comparison is made between the distributions of unevaporated fragments of bodies disrupted in the atmosphere and the distributions obtained after the disruption of bodies in experiments. Some regularities in meteorite distributions and the influence of the incompleteness of the available collection of meteorites on their mass distribution are discussed.

描述陨石雨中的碎片质量分布
碎片的质量分布是一个重要的特征,通常需要对其进行定义,以便对打散的流星体和小行星与大气层的相互作用进行前瞻性建模,在一定程度上可以通过坠落地面的陨石的分布来推断。在之前的研究中,我们推导出了一个关于被破坏天体碎片质量分布的公式,假定该分布以微分形式存在幂律,并应用该公式描述了许多模拟外太空小行星碎裂的撞击实验结果。该公式将碎片的累积数量表示为碎片质量(归一化为总质量)、最大碎片的质量分数和幂指数的函数,而幂指数是唯一可调整的自由参数,可使分析分布与经验分布达到最佳拟合。在这里,我们使用所提出的公式来描述 13 个地外天体在大气层中通过和破坏后坠落地面的回收陨石的质量分布,以及在撞击实验中被破坏的陨石样本碎片的质量分布。对在大气层中被破坏的天体未蒸发碎片的分布和在实验中天体被破坏后的分布进行了比较。讨论了陨石分布的一些规律性以及现有陨石收集的不完整性对其质量分布的影响。
