Numerical Simulation of the Long-Term Thermal Evolution of the Nuclei of Short-Period Comets Using the Nucleus of Comet 67P/Churyumov–Gerasimenko as an Example

Dorofeeva, V. A.; Marov, M. Ya.; Rusol, A. V.

Using numerical models, we have studied what depth of the outer layer the comet nuclei are degassed to when they are in orbits whose perihelion is close to the Sun for tens of years. The problem is topical, because it helps to understand how much the experimentally obtained results on the composition of comet comas depend on how long the comet is …
