In this work, we show a study about the formation and evolution of minor planet reservoirs in planetary scattering scenarios around of M0-type stars with 0.5 M. To carry out this study, we use two numerical codes. On the one hand, we use a semi-analytical model to determine the properties of the disk able to form three giant planets close to the stability limit. On the other hand, we use a -body code in order to study the evolution of the three giant planets and the minor planet reservoirs. Our results suggest the existence of minor planet populations with very different orbital characteristics as well as a wide variety of planetary architectures. An important result is the formation and stability of small bodies reservoirs called resonant clouds.
