ESTIMATION OF INDEX MASS OF PERSEID, ORIONID AND GEMINID METEOR SHOWERS BY THE GLOBAL METEOR NETWORK DATA

Abstract

The mass distribution of meteoroids is described by a power law, where the degree exponent is the parameter s. The parameter s of selected meteoroid streams (Perseids, Geminids, and Orionids) was calculated for 2021–2022 from the Global Meteor Network (GMN) data. Parameter s estimate was based on photometric estimates of meteoroid masses and mass estimates from empirical relationships. The variation of the s estimates during the period of activity of selected meteoroid streams was analyzed. It was found that  the influence of different estimates of particle masses on the parameter s can reach 20%.
