Abstract
We consider the thermal emission of photons and e+e- pairs from the bare quark surface of a hot strange star. The radiation of high-energy (20 MeV) equilibrium photons prevails at the surface temperature TS 5 × 1010 K, while below this temperature, 8 × 108 K TS < 5 × 1010 K, emission of e+e- pairs created by the Coulomb barrier at the quark surface dominates. The thermal luminosity of a hot strange star in both photons and e+e- pairs is estimated.Keywords
