In its simulations, the starting disk decides whether a system ends up with similar-mass planets. Beyond that, dynamical interactions such as planet-planet and planet-disk encounters influence whether it becomes mixed, anti-ordered or ordered. If it holds beyond the model, it would help link observed architectures to the conditions in which systems formed.","findings":["Almost all systems from disks with initial solid mass below one Jupiter mass are similar, while heavier disks can produce mixed, anti-ordered or ordered systems.","Increasing dynamical interactions tends to shift architecture from mixed to anti-ordered to ordered.","The model predicts a metallicity-architecture correlation: similar systems are very common around low-metallicity stars, and anti-ordered and ordered systems become more common as metallicity rises."],"terms":[{"term":"architecture classes","means":"Four categories describing how planet masses are arranged within a system: similar, mixed, anti-ordered and ordered."},{"term":"initial conditions","means":"The starting properties of the system, such as the mass of solids in the protoplanetary disk from which the planets form."},{"term":"nurture","means":"The effect of later processes, such as interactions between planets and with the disk, on a system's final architecture."}],"basis":"abstract","abstractFrom":"arxiv","model":"claude-sonnet-5-5","writtenAt":"2026-10-21T17:15:59.902Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-21T17:15:59.902Z","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.
