Relation of v_∞−T_eff for different studies that made hydrodynamically consistent sequences of models in which T_* varied. The black lines indicate the empirical relation by Hawcroft et al. (2024) (the solid line represents the actual relation, and the dashed line indicates the relation shifted arbitrarily). The pink and violet squares indicate the models by Sander et al. (2023) and Lefever et al. (2025), respectively. The blue circle indicates the models of Sabhahit et al. (2026) with Γ_e ∼ 0.35, and the green circle indicates the models of Björklund et al. (2021) with similar Γ_e. The red and brown diamonds indicate our sequence of models and show the rarefied and dense solutions, respectively. The lower panel is a zoom-in of the region within the dotted rectangle in the upper panel.
