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.
