Sublimation activity of a comet and its visibility on the night sky

Abstract

The paper presents an analysis of the sublimation activity of a hypothetical comet as a function of its heliocentric distance. The study shows that the change in brightness of the comet for a fixed heliocentric distance depends significantly on the change in the size of this part of the comet nucleus surface, which is sublimation active. The paper also includes the related discussion of visibility of the selected comets depending on the degree of light pollution of the night sky.
