A model of dust fragmentation in near-nucleus jet-like features on Comet P/HalleyA model for dusty gas flows and dust fragmentation in cometary atmospheres is developed and applied to interpret the dust intensity profiles near the nucleus of Comet P/Halley. It is found that fragmentation is not the only physical mechanism for explaining the dust intensity profiles from the 1/z dependence in the region about 1 to 40 km from the nucleus. A combination of the geometric effect and dust fragmentation is a likely explanation for the profiles.
