The claim says that, in the simulations, the amount of dynamical interaction (planets disturbing each other or exchanging effects with the disk) is linked to which class a system ends up in. If it holds, it would help explain how a system's final mass arrangement is shaped by its history, not just its starting conditions. It is a result for model-generated systems, so it is a prediction for observers to test.","findings":["Almost all systems from disks with initial solid mass below one Jupiter mass are similar, while heavier disks can give mixed, anti-ordered or ordered systems.","Increasing dynamical interactions tends to shift architectures from mixed to anti-ordered to ordered.","The model predicts a metallicity-architecture correlation, and nature (initial conditions) decides whether a system is similar, while nurture influences the other classes."],"terms":[{"term":"architecture classes","means":"Four categories of planetary system (similar, mixed, anti-ordered, ordered) that describe how planet masses are arranged within a system."},{"term":"planet-disk interaction","means":"The gravitational and other exchange of momentum between a forming planet and the gas and dust disk around the young star."},{"term":"planet-planet interactions","means":"The gravitational effects planets in the same system have on each other's orbits and growth, such as scattering or collisions."}],"basis":"abstract","abstractFrom":"arxiv","model":"claude-sonnet-5-5","writtenAt":"2026-10-21T17:45:54.527Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-21T17:45:54.527Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
