Scientific paper

Shoemaker-Levy 9 Comet fragments intruding into the Jovian atmosphere form a wake, i.e., a hot, luminous, dissociated and ionized column. This wake expands and becomes a rarefied channel. In the dense atmosphere cracks grow in number and size and the fragment deforms as a liquid. Under aerodynamic load the meteoroid is additionally fragmented due to growth of instabilities. A cloud of small fragments decelerates, disintegrates and is vaporized. Debris and atmospheric gas escape through the rarefied wake formed at the "bolide" stage of the impact and stretched along the trajectory. A fireball, or a plume, rises to high altitudes due to nonuniformity of atmospheric density. Later, the ejected gas falls back onto the atmosphere causing atmospheric oscillations and heating.
