P51 v2 — Errata: Corrected aₘax/M = 0. 356–0. 503

Puntos clave

This erratum aims to correct key values related to the ergoregion and stability of CCEGA black stars.
Correction of Table 3 from P51 v2.0 regarding a_max/M value.
Adjusted value calculations based on new density parameters (ρ_c = 7.4 ρ_nuc).
Analytical verification of rotational stability in CCEGA black stars.
Corrected a_max/M value is 0.356–0.503, improvement over previous miscalculation of 0.7–0.9.
Ergosphere confirmed to be inside the stellar surface for all masses at maximum spin.
No evidence of ergoregion instability as previously claimed, confirming structural stability.

Resumen

"Corrects Table 3 of P51 v2. 0: value 0. 7–0. 9 was R/Mgeom (=1/C), not aₘax/M. Correct value is 0. 356–0. 503. " Correction to v1. 0. C = 0. 44 was incorrect (used ρc ≈ 2. 6 ρₙuc implicitly). Correct value with ρc = 7. 4 ρₙuc gives C ≈ 0. 63–1. 27. Ergoregion is exterior to the object for all masses. Ergoregion instability claim retracted. Rotational stability recovered via P60 (geometric suppression mechanism). Analytical verification that CCEGA black stars (4. 56–12. 0 M☉, C ≈ 0. 44) are rotationally stable. Light ring confirmed at r = 3GM/c². Ergosphere buried inside stellar surface for all masses at maximum spin. No Friedman (1978) ergoregion instability. Maximum rotation 0. 76–2. 0 kHz. Stability is structural consequence of ρc = 7. 4 ρₙuc. Keywords: CCEGA, black stars, ergoregion instability, light ring, rotation, compact objects, angular momentum
