Thermal emission from bare quark matter surfaces of hot strange stars
Abstract
We consider the thermal emission of photons and electron-positron 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 x 1010 K, while below this temperature, 8 x 108 < TS < 5 x 1010 K, emission of electron-positron pairs created by the Coulomb barrier at the quark surface dominates. The thermal luminosity of a hot strange star in both photons and pairs is estimated.
