THE FORMATION OF STRIATED STRUCTURES IN DUST TAILS OF COMETS

С. В. Харчук, П. П. Корсун

Abstract


The mechanism of formation of striae structures in the dust tails of comets is proposed. There are local active areason the surfaces of comet nucleus. The formation of striae is indebted to the different rate of dust ejection from activeareas depending on that they are located on the sunlit or shaded side of the rotating nucleus. The model analysis ofdust tails forming of comets C/1957 P1 (Mrkos), C/1962 C1 (Seki-lines), C/1910 A1 (Great January Comet), C/1975V1 (West) showed that the proposed mechanism can explain the formation of striae.

Keywords
