The paper presents a new approach to determining the change in the brightness of a comet during an outburst. It was investigated how the porosity of the dust particle translates into an increase in comet brightness during an outburst. It has been sho

In this paper, we investigate the conditions for the local ejection of a metamorphosed surface layer of material from a comet. We have calculated the strengthening of the material of the nucleus of comet 67P/Churyumov–Gerasimenko and the increase o

The sublimation of ice covered by dust is a common way of outgassing of comets. The rate of this process depends on the thermal conductivity and permeability of dust, as well as the properties of the ice itself. It can be calculated using the Hertz-K

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 po

On the nucleus of comet 67P/Churyumov-Gerasimenko numerous pits and depressions of different sizes are identified. In the present work the origin of depression Hatmehit is investigated. We propose a mechanism that includes recession of the surface du

In this work we investigate trajectories and regions of deposition of material ejected from depression Hatmehit on comet 67P/Churyumov–Gerasimenko. This depression, located on the lobe Head, could be a result of endogenic, possibly still ongoing, a

Evolution of the surfaces of cometary nuclei is determined by the sublimation of ice. The rate of sublimation is commonly calculated using the simple Hertz–Knudsen formula, which should be corrected by a temperature dependent sublimation coefficien
