Abstract

fetched live from OpenAlex

In this work the stability of all equilibrium points in the photogravitational relativistic restricted three-body problem (RTBP) with oblate primaries is investigated for arbitrary RTBP systems. The four roots of the RTBP systems constituted from the Sun–planet of the solar system are computed as a computational example. The computation emphasizes the instability of all collinear points in the whole range of mass ratio. In the case of triangular points, the stability regions are affected differently according to the kind of perturbations. The different cases are plotted as well as analyzed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
