Erratum: Unified equations of state for cold non-accreting neutron stars with Brussels-Montreal functionals. I. Role of symmetry energy
Bibliographic record
Abstract
This is a correction notice for ‘Unified equations of state for cold non-accreting neutron stars with Brussels-Montreal functionals. I. Role of symmetry energy’ (DOI: https://doi.org/10.1093/mnras/sty2413), which was published in MNRAS 481, 2994–3026 (2018). We regret to inform that a computing error in the inner-crust code for functionals BSk24 and BSk25 came to our attention after publication. The correction of this error leads to the approximate proton drip point (Table 12) being shifted from |$\bar{n}_\mathrm{pd}=0.069$| fm−3 to |$\bar{n}_\mathrm{pd}=0.073$| fm−3 for functional BSk24 and from 0.077 fm−3 to 0.081 fm−3 for functional BSk25. The tables appearing as supplementary material have been appropriately modified. The functionals BSk22 and BSk26 were calculated correctly, but all the tables appearing as supplementary material have been corrected for errors in formatting. Upper panel: Equilibrium values Zeq of number of protons in a Wigner-Seitz cell in the inner crust (solid symbols) and Zcl, the cluster component of Zeq (open symbols), as functions of mean baryon density |$\bar{n}$| for functionals BSk24 and BSk25. The arrows indicate the proton-drip densities |$\bar{n}_\mathrm{pd}$|. Old and corrected data are coded according to the legend. Lower panel: The same for the neutron numbers Neq and Ncl. The curves represent the fit with the corrected input values of |$\bar{n}_\mathrm{pd}$| and Zeq. The main feature of the correction is for a new magic number at Z = 138 to appear just below proton drip in the case of functional BSk25, in the density range from 0.077 fm−3 to 0.081 fm−3. Some related quantities, such as the numbers of free and clustered protons and neutrons in a Wigner-Seitz cell, have changed accordingly, while the changes in the numerical values of some other quantities, for example pressure, energy density, and proton number fraction, are negligibly small. The analytic fitting formulae described in Appendix C remain unchanged, with the new residuals of the same order of magnitude as originally. Although the numerical values of some of the fitted quantities have changed in the density ranges between the old and new values of the proton-drip densities, the fitting formulae reproduce these changes after the above-mentioned tabular values of the proton drip densities and Z have been fixed (the Fortran code that implements the fits, which is available at http://www.ioffe.ru/astro/NSG/BSk/, has been updated accordingly). The figure illustrates the changes in the equilibrium values of the proton and neutron numbers in a Wigner-Seitz cell and in a cluster.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
