MICROWAVE-BURSTS FROM JUPITER DUE TO K-FRAGMENT, N-FRAGMENT, P2-FRAGMENT AND S-FRAGMENT

This article reports the observations of microwave emission from Jupit er during the impact of K, N, P2 and S fragments of the comet Shoemake r-Levy 9. The comparison of microwave bursts intensities produced by t hese impacts with the impact class and the size of the impactors revea ls no correlation. This is in conformity with other observations at mi crowave frequencies and indicates that the process of burst emission i s very complex. The impacts K and N produced three microwave bursts wh ich could possibly be due to further fragmentation of these fragments. The results are discussed in the perspective of synchrotron emission from Jupiter and possible enhancements due to an increase in the radia l diffusion coefficient. However, this model does not fully explain th e observations.
