“…Recent study of quark stars has focused on their evolution within full general relativity (Zhou et al 2021;Zhu & Rezzolla 2021), their cooling (Zapata et al 2022), finite temperature effects (Chu et al 2019(Chu et al , 2021, strong rotation (Sun & Huang 2022) and differential rotation (Szkudlarek et al 2019), effects from the presence of magnetic field (Terrero et al 2021), limits on possible electric charge (Gonçalves & Lazzari 2020;Estevez-Delgado & Estevez-Delgado 2022), and the effects of modified gravity (Deb et al 2019). Constraints from gravitational waves observations on strange stars were discussed in Mannarelli & Tonelli (2018) and Cao et al (2022), and the onstraints on the mass-radius relationship in observations of the compact object HESS J1731-347 were established in Oikonomou & Moustakidis (2023), Rather et al (2023), andSagun et al (2023).…”

The mechanism of pair creation in the electrosphere of compact astrophysical objects such as quark stars or neutron stars is revisited, paying attention to evaporation of electrons and acceleration of electrons and positrons, which were previously not addressed in the literature. We perform a series of numerical simulations using the Vlasov–Maxwell equations. The rate of pair creation strongly depends on electric field strength in the electrosphere. Although Pauli blocking is explicitly taken into account, we find no exponential suppression of the pair creation rate at low temperatures. The luminosity in pairs increases with temperature and it may reach up to L ± ∼ 1052 erg s−1, much larger than previously assumed.
