Abstract

fetched live from OpenAlex

We present a new exact solution of charged anisotropic Tolman VII type solution representing compact stars. Here the transverse pressure and sound speed are decreasing in nature and well behaved. These solutions can be used to model both neutron star and quark star within the range of observed masses and radii. For particular values of constant parameters, we present a neutron star of mass 0.924 [Formula: see text] with radius 11.55 km and a quark star of mass 0.7 [Formula: see text] with radius 8.76 km. The model predicts a surface gravitational redshift of 0.145 for a particular choice of constant parameters. Also, the compactness parameter (i.e., M/R = 0.119) is less than 4/9 and satisfies the Buchdahl–Andréasson limit. Indeed, our charged anisotropic solution also satisfies the Cooperstock and De La Cruz condition as M/Q = 13.74 > 1, which is needed for a configuration to be at equilibrium.

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.
