Abstract

fetched live from OpenAlex

Charged-particle motion in the spacetime of a weakly magnetized static nonrotating black hole is investigated. We study the conditions under which a charged particle originally revolving around the black hole in a circular orbit after being kicked by another particle or photon can escape to infinity. The escape velocity for particles at the innermost stable circular orbits is determined and the properties of particles moving with near-critical velocity are discussed. We show that in a general case such motion is chaotic.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
