Abstract

Evidence of waves has been observed in Hubble Space Telescope (HST) images of the Comet Shoemaker-Levy 9 impact sites [H. B. Hammel et al.,''HST imaging of atmospheric phenomena created by the impact of CometShoemaker-Levy 9,'' Science 267, 1288-1296 (1995)], The radius of a ring that appears near the fragment G impact site is consistent with anacoustic wave and increases with time. This feature cannot be explained in terms of a naive plane-wave model because it appears to expand at a rate that is slower than the speed associated with its radius. This behavior can be explained in terms of multipath propagation in the sound channel. According to this hypothesis, acoustic waves corresponding to different group speeds followed paths that passed in and out of the relatively thin debris layer in which the feature appears. Matched-field processing for the depth of the source indicates that the fragment G explosion must have occurred deep in the water clouds if the ring indeed corresponds to an acoustic wave.
