The temperature regime and the total flux of sublimation from an active region on a cometary nucleus. Effect of rotation
Abstract
This work presents the results of calculation of the temperature regime and the total flux of sublimation for a new physical model of local active areas on a cometary nucleus. As it was shown before a conical hole in the surface dust layer of a cometary nucleus can work as a concentrator of the solar energy and, therefore, intensifies sublimation. The temperature of ice on the bottom and that of dust on the side of a crater is calculated for different geometrical parameters of the crater and different conditions of rotation of the nucleus. The dependence of the effect of the location of this active region as well as the effect of day-night alternation is investigated.
