Resonance behaviour of the observed HIP 29442 system and the synthetic system analogues. The top panel shows the HIP 29442 system (red star) with respect to the web of three-body MMRs (in black) and two-body MMRs (in purple and red). The coloured circles show the position of the triplets of the analogue systems from the synthetic NGPPS population, the system ID corresponding to each colour is given on the x-axis of the bottom panel. The bottom panel shows the same triplets with their relative distance to the nearest three-body MMR. The coloured lines show the distance to three-body MMRs for the observed systems HIP 29442, K2-138 and TOI-178.
