Study derives tidal charge in black stars, suggesting a new physical origin for existing results.
We derive the tidal charge q of CCEGA black stars directly from the Israel junction conditions, without invoking the bulk Weyl tensor E_μν. This resolves the tension between P35 (q ≠ 0) and P55 (bulk Weyl tensor = 0). The result q_Israel = 2G_N·M·R_final·(1−e⁻¹)/c² is consistent with P35 numerically but has a different physical origin. No retraction of P35 is required.
