Dynamics of spherical stars with structure scalars and <i>R</i> + <i>ϵR</i><sup><i>n</i></sup> cosmology
Bibliographic record
Abstract
We study the role of the R + ϵR n model on the dynamical evolution of radiating anisotropic and shearing viscous relativistic spherical stellar structures. In this context, we calculate modified versions of scalar functions (previously defined by L. Herrera et al. Phys. Rev. D, 79, 064025 (2009). doi:10.1103/PhysRevD.79.064025 ) for the problem under consideration and then associate them with the physical parameters. The Weyl tensor as well as other matter variables with extra curvature terms coming from the model are related and find shear and expansion evolution equations. We conclude that structure scalars along with f(R) degrees of freedom have vital importance in the dynamics of spherical compact systems.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
