TL;DR

This paper studies how electric fields in the electrosphere of quark stars influence photon emission, finding that Coulomb field-induced bremsstrahlung dominates over other mechanisms at certain temperatures.

Contribution

It introduces a detailed analysis of photon emission mechanisms in quark star electrospheres, highlighting the dominant role of Coulomb field bremsstrahlung at specific temperatures.

Findings

Coulomb field bremsstrahlung surpasses electron-electron bremsstrahlung.

Photon emission from pair creation is less significant.

Temperature range where this mechanism dominates is identified.

Abstract

We investigate the photon emission from the electrosphere of a quark star. It is shown that at temperatures $T\sim 0.1-1$ MeV the dominating mechanism is the bremsstrahlung due to bending of electron trajectories in the mean Coulomb field of the electrosphere. The radiated energy flux from this mechanism exceeds considerably both the contribution from the bremsstrahlung due to electron-electron interaction and the tunnel $e^{+}e^{-}$ pair creation.
