The three inner satellites (Io, Europa, Ganymede) are involved in a 4:2:1 mean motion resonance (MMR) chain, while Callisto is situated beyond the 2:1 MMR with Ganymede (Peale, 1999). The current distances of Io, Europa, Ganymede, and Callisto from Jupiter are 5.9RJ, 9.4RJ, 15RJ, and 26.4RJ, respectively (Schubert et al., 2004), where RJ is the radius of Jupiter. All of these satellites have masses on the order of 10-5 masses of Jupiter (MJ). Within the orbit of Io, there is a population of small moons around Jupiter, namely Metis, Adrastea, Amalthea, and Thebe. Metis and Adrastea have sizes approximately around 21.7km and 8.2km, in nearly circular and coplanar orbits. In contrast, Thebe and Amalthea are considerably larger, with diameters of about 49.2km and 83.6km, respectively. These small moons are nearby or embedded in the ring system of Jupiter. The formation and evolution of small satellites remain inconclusive. The goal of this work is to evaluate the efficiency of satellite implantation, during the formation of Galilean satellites, interior to the orbit of Io, focusing on their potential to evolve into orbits similar to those of Jupiter's small inner moons. To achieve this, we performed N-body numerical simulations to model the implantation of satellitesimals, initially distributed between 5RJ and 100RJ, in the region of the small moons (

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
