Left: M vs log r plot for various values of T_pin. (a) T_pin = 3.1 × 10¹¹ K, (b) T_pin = 5.605 × 10¹¹K, (c) T_pin = 6.04 × 10¹¹ K, (d) T_pin = 6.460 × 10¹¹ K, (e) T_pin = 6.554 × 10¹¹ K and (f) T_pin = 7.0 × 10¹¹ K. Global solutions are represented by solid lines. Panel g: vs T_pin. Solid black curve is for the solutions passing through outer sonic point, while dotted black curve is for solutions passing through inner sonic point. Panels a–f: solutions corresponding to the points marked in right panel g. The disc flow parameters are E = 1.0015, λ = 2.6 and Ṁ = 0.02 Ṁ_Edd. The space-time is described by a BH of mass 10 M_⊙.
