BULK DENSITIES OF METEOROIDS

The article deals with the results of application of the method for de termination of meteoroid bulk densities, based on the physical theory of meteor phenomenon taking into consideration husking type of fragmen tation of meteoroids, to more than 1100 meteors compiled in catalogues of photographical and TV meteors. Our results indicate that both the sporadic and shower meteors can be caused by various kind of bodies ra nging from fluffy dust clumps to iron or stony-iron meteoroids. We hav e arrived at the conclusion that the fragmentation itself cannot be co nsidered as sufficient criterion of structure of meteoroids. The conce pts of husking followed slightly more than 230 meteors from the whole sample. As a particular result, we arrived also at the conclusion that while Perseids are produced namely by dust clumps particles Geminids are formed by stony-iron kind of meteoroids.
