Electron-Positron Pair Production in the Electrosphere of Quark Stars

摘要: We study Schwinger pair creation of charged particles due to the inhomogeneous electric field created by thin electron layer at surface quark stars (the electrosphere). As suggested earlier, low photon emissivity quark-gluon plasma and electrosphere, electron-positron emission could be main observational signature stars. To obtain rate we use tunneling approach. Explicit expressions for fermion per unit time volume are derived, which generalize classical result. The finite-size effects in production, presence a boundary star), also considered framework simple It is shown that induce large quantitative qualitative deviations particle production from what one deduces with formula its generalization electrosphere. flux electrosphere considered, magnitude these parameters estimated. Due inhomogeneity distribution effects, high temperatures (T ≥ Tcr ≈ 0.1 MeV) find lower than previously numerical value critical temperature depends on potential star. briefly consider effect magnetic process show can drastically enhance rate.
