The evolution of gently sloping mantled deposits on comet 67P/Churyumov-Gerasimenko
چکیده انگلیسی
We investigated the role of local illumination and material parameters that can be important in determining evolution of a gently inclined slopes on the nucleus of comet. The considered material parameters are: size of ice grains, agglomerates and pores in-between, thermal conductivity of dust mantle, size of pores in the dust mantle, presence of organic admixtures in water ice, difference of bonds between agglomerates composing the dust mantle and bonds in the underlying ice-dust material, thickness of the layer of dust. The simulations were performed for the selected locations in the north part of the small lobe of the comet. We have found, that the rate of erosion is sensitive to the granulation of material, that is not the case in the region Hatmehit (Kossacki and Czechowski, 2018). The erosion may lead to the formation of small-scale pits.
