The paper discusses four processes that may be responsible for shaping the relief of the comet landscape. The considerations take into account the following phenomena: intense sublimation of cometary ice, emission of dust from the surface comet and through jets, migration of dust on the cometary surface, and destruction of fragment the nucleus surface in the context of a change in cometary brightness. These processes appear to be of key importance for the formation of an irregular comet nucleus structure. It should be remembered that the processes discussed in this paper have an impact on the relief of the surface, but on a longer time scale, i.e., more than a few orbital periods.

影响彗星景观结构的选定现象

该论文讨论了可能导致彗星景观起伏的四个过程。考虑考虑到以下现象：彗星冰的强烈升华，从彗星表面和通过喷射流的尘埃发射，彗星表面尘埃的迁移，以及在彗星亮度变化的背景下原子核表面的碎片破坏. 这些过程似乎对于形成不规则彗核结构至关重要。应该记住，本文讨论的过程对地表的起伏有影响，但时间尺度较长，即多于几个轨道周期。
