Formation of multiple dynamical classes in the Kuiper belt via disk dissipation by TCH Lau @birnstiel.bsky.social @stammler.bsky.social @astrojoanna.bsky.social

arxiv.org/abs/2509.21437
Formation of multiple dynamical classes in the Kuiper belt via disk dissipation Tommy Chi Ho Lau, Til Birnstiel, Sebastian Markus Stammler, Joanna Drążkowska Planetesimal formation likely lasted for millions of years in the Solar nebula, and the cold classicals in the Kuiper belt are suggested to be the direct products of streaming instability. The presence of minor planetary bodies in the outer Solar System and the exo-Kuiper belts provide key constraints to planet formation models. In this work, we connected dust drift and coagulation, planetesimal formation, N-body gravity, pebble accretion, planet migration, planetary core accretion, gap opening, and internal photoevaporation in one modeling framework. We demonstrate that multiple classes of minor planets, or planetesimals, can form during disk dissipation and remain afterwards, including a scattered group, a resonant group and a dynamically cold group. Significant growth by pebble accretion was prevented by both dynamical heating due to the giant planet in the system and rapid dispersal of the disk towards the end of its lifetime. We also conducted a parameter study which showed that this is not a universal case, where the outcome is determined by the competition for dust between planetesimal formation and pebble accretion. Combining this scenario with sequential planet formation, this model provides a promising pathway towards an outer Solar System formation model. 20 pages, 5 figures. Accepted for publication in ApJ
