AB: The dust particles dynamics in the outer Solar System has been a subject of study in the last decades, particularly in Jupiter where the space exploration has provided many interesting results that have been used to create several models related to the formation of dust structures, as the streams escaping from the Jovian magnetosphere or the tenuous rings via the capture of small rocky bodies. In this work a model is presented in order to analyze the dynamical behavior of captured micrometeoroids as part of the formation of tenuous annular structures around Jupiter or as part of the rocky material that can escape from the planetary magnetosphere. The model includes several forces that modulate the dynamics of these tiny bodies once they have been caught by the Jovian system. The results show that there are two preferential sizes of micrometeorites to be captured, these tiny dust particles remain around this planet, at least 5 years, describing a butterfly-like distribution located inside a latitudinal belt.
