The model of the quasi-continuous fragmentation
Abstract
The amount of data evidencing fragmentation led Levin (1963) to the conclusion that, if fragmentation was not taken into consideration in processing the observations, erroneous result would results. Knowledge of sizes and masses of particles, which separate from a meteor body or on which it is fragmented during moving in atmosphere of the Earth, is of interest for understanding of processes of its interaction with air, and for improvement of our notion idea of a structure of meteor bodies. The new formula, describing an appearance of fragmentation is obtained on the basis of a new mathematical model approach to solution of the task about fragmentation of a meteoric body of quasi-continuous type. The new approach has allowed describing two kinds of quasi-continuous fragmentation (QCF) of uniform mathemaical formula. The limiting case slow QCF is the pure evaporation and the limiting case fast QCF is the flares of meteors in its classical definition are exhibited.
