Sub-Neptune exoplanets, those with radii between that of Earth and Neptune, can give researchers clues about their relationship to other planets within their host systems. While there have been significant detections of sub-Neptune exoplanets in multiple systems, determining whether they formed as individual planetary embryos or resulted from fragmentation events that created sibling planetesimals remains a challenge. By comparing the system architectures and observational features of known sub-Neptune systems through a statistical analysis that considers the presence of inner and outer companions, as well as dynamical stability assessments, we aim to improve our understanding of their birth scenarios. Ultimately, such studies enhance our knowledge of planet formation processes and system dynamics as a whole.
