Description
A bare strange star is bounded by a thin electron layer, the electrosphere, whose overcritical field produces electron–positron pairs through the Schwinger mechanism. We re-examine this by integrating the relativistic Vlasov–Maxwell system, with a Schwinger pair-production source and the full two-current field equation, on a finite-temperature electrosphere background. We show that the surface pair-creation rate is governed by how well the sharp Fermi edge in the Pauli-blocking factor is resolved. The rate converges to the Usov value, about $2\times10^{53}\,\mathrm{s^{-1}}$ at $T=3\,m_{\mathrm{e}}$. The surface field is not enhanced, the kinetic field follows the electrostatic solution where pairs form. Including relaxation-time collisions reduces the pair luminosity by a few percent.
