摘      要：We analyze the thermodynamic model of changes in comet brightness focusing on the exceptional case which is comet 29 P/Schwassmann-Wachmann(hereafter 29 P/SW). This object demonstrates quasiregular flares that occur in a short period of time; most often it lasts about a dozen hours. The analysis of observational data shows that the average number of comet outbursts for 29 P/SW is 7.3 per year. This is the only known comet with such a number of outbursts per year, which demonstrates its uniqueness. In the proposed approach to analyze the outburst of comet 29 P/SW, we took into account the complex structure of particles which are in its coma and assumed that they are composed of water ice, dust and organic *** paper explains how this diversity affects the more efficient scattering of incident sunlight during the outburst of comet 29 P/SW.
