calculations take into account total scattering cross-sections coming from ice, dust particles,
and their combinations. It was assumed that dust particles are so-called silicate
agglomerates which consist of single monomers. We analyze the actual outburst of the
interstellar comet 2I/Borisov in terms of mass loss. This parameter (mass ejected) is one of
the main factors determining the amplitude of the comet's brightness jump. A numerical …
