Conditions for the formation of anomalous tail of comet

Safarov, Abduljalol G.; Ibadinov, Khursand I.

The time and velocity of ejection of dust particles of anomalous tails from cometary nuclei are determined. It is revealed that some comets cause the formation of an anomalous tail is the collision of their comet nucleus with other bodies of the Solar System. An investigation of the formation conditions of the anomalous tail shows that the dust ej…

Thermal Evolution of the Nucleus of the Comet 67P for 120 Years: Numerical Simulations

Rusol, Andrey V.; Dorofeeva, Vera A.

The purpose of this paper is to estimate to what temperatures and to what depth the outer layers of the cometary nuclei are heated for several dozen revolutions around the Sun, and what changes in the composition of the volatiles occur in this case. This is important because it is not clear how much the experimentally obtained results on the compo…
