The paper presents an analysis of the actual brightness change of comet 73P/Schwassmann-Wachmann, which took place in 1995. The consequence of a cometary outburst is the destruction of a fragment of its surface. This causes the emission of comet material from both the surface and from exposed subsurface layers. Therefore, the calculations take into account the scattering cross-sections that come from ice and dust particles. It was assumed that the dust particles are silicates which are characterized by high irregularity of their structure. This assumption is a consequence of the analysis of the results provided by the Rosetta mission to the comet 67P/Churyumov-Gerasimenko. The main factor determining the amplitude of a cometary outburst is the mass ejected as well as the loss of ice that holds the individual nucleus structures together. Consequently, this phenomenon can significantly contribute to the destruction and even decay of the cometary nucleus.

彗核的毁灭——以73P/Schwassmann-Wachmann为例

该论文分析了 73P/Schwassmann-Wachmann 彗星在 1995 年发生的实际亮度变化。彗星爆发的后果是其表面的碎片遭到破坏。这导致彗星物质从表面和暴露的地下层发射。因此,计算考虑了来自冰和尘埃颗粒的散射截面。假设尘埃颗粒是硅酸盐,其特征在于其结构的高度不规则性。这一假设是对 Rosetta 任务对彗星 67P/Churyumov-Gerasimenko 提供的结果进行分析的结果。决定彗星爆发幅度的主要因素是喷出的质量以及将单个核结构保持在一起的冰的损失。
