Points in the ﹩{{ \mathcal M }}_{\infty }﹩–ϵ_ρ space representing flow parameters for simulations performed with the “wind tunnel” setup. For polytropic envelopes, each combination of ﹩{{ \mathcal M }}_{\infty }﹩ and ϵ_ρ has a corresponding q_r value (MacLeod et al. 2017). Simulations are shown on lines of constant q_r, with the exception of three simulations from MacLeod & Ramirez-Ruiz (2015a) that do not follow the polytropic relation. The simulations in this work expand on the previous work as labeled, extending across both axes to higher Mach numbers and steeper density gradients, significantly extending coverage across the region of parameter space realized in realistic stellar profiles as detailed in Everson et al. (2020).
