Abstract:
Comparison of mass distributions of unevaporated fragments of meteoroids and asteroids disrupted in the atmosphere and fragments of bodies disrupted in impact experiments modelling the destruction of asteroids in outer space is carried out. For the analytical description of distributions, a relation is used that is derived under the assumption that the distribution density of the number of fragments over masses obeys a power law. The ranges of variation of the power index are estimated in both cases. Approximate dependencies of the power index on the specific impact energy (destruction in experiments) and on the number of fragments (destruction in the atmosphere) are obtained.
Key words:meteoroid, asteroid, fragmentation, mass distribution.
