Theory 94/Cosmic/Planetary systems
Architecture Is Migration Against Disk Life
The claim
Planetary system architecture is set by the ratio of migration rate to disk lifetime, so systems that migrate far have long-lived disks.
01Mechanism
Migration moves planets inward while the disk lasts; when the disk disperses, the architecture freezes.
02Prediction
Architecture should track the ratio.
03Refutation
Architecture tracking initial position would remove migration.
