Simulated Trappist-like systems from the planetesimal accretion scenario (top 6 rows) and the pebble accretion scenario (bottom 6 rows). Periods are shown on the x-axis and planet masses are indicated by the symbol size. Resonances are also shown between neighbouring planets and when relevant, between non-neighbouring planets. The systems highlighted in bold represent those described in Sects. 3.2 and 4.4 for the planetesimal and pebble accretion scenarios respectfully. The Trappist-1 system is shown in between the two scenarios for comparison.
