Abstract

fetched live from OpenAlex

Abstract Magnetars form a subclass of neutron stars characterized by magnetic fields of order 1014 − 1015 G at their surface. According to numerical simulations, the magnetic fields in their interior could potentially be even stronger. Such magnetic fields are so extreme that the internal constitution of neutron stars may be altered. The effects of Landau-Rabi quantisation of electron motion on the equation of state and on the equilibrium composition of the crust of a neutron star are investigated for a wide range of magnetic field strengths. Both the outer and inner parts of the crust are treated in a unified and consistent way within the nuclear-energy density functional theory.

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.
