Comparison of mass-loss rates from prescriptions by Vink et al. (2001), Björklund et al. (2023), Krtika et al. (2024) over the temperature range from 60 to 12.5 kK. Key stellar parameters in the left panel are: log₁₀(L_⋆/L_⊙) = 5.3, M_⋆ = 25 M_⊙ and, Z = 0.5 Z_⊙. This results in Γ_e = 0.21. In the right panel adopted properties are log₁₀(L_⋆/L_⊙) = 5.6, M_⋆ = 25 M_⊙ and, Z = 0.5 Z_⊙, yielding Γ_e = 0.42. The full lines signify that the result of the fit-formulate given by these authors are shown rather than the actual underlying model-sets. For the Vink et al. (2000) rates, for which a mass-loss jump is identified to cover the regime ∼22.5 − 27.5 kK, enforcing a strict discontinuity (i.e. at a single temperature) implies that the size of the Ṁ-jump is somewhat enhanced as compared to the underlying models.
