Thermal properties of regular black hole with electric charge in Einstein gravity coupled to nonlinear electrodynamics Project supported by the National Natural Science Foundation of China (Grant Nos. 11504027 and 11847011). |
The relationship between radii of horizons and parameter χ with some fixed values of λ. Dashed horizontal line represents radius of extremal black hole rE corresponding to χ = χE. Panel (a): rE ≈ 0.668M and χE ≈ 0.666M for λ = 0.1M. Panel (b): rE ≈ 0.805M and χE ≈ 0.582M for λ = 0.5M. Panel (c): rE ≈ 1.004M and χE ≈ 0.41M for λ = 0.75M. Panel (d): rE ≈ 1.263M and χE ≈ 0.102M for λ = M. |
