Polarization levels for the 12 simulations of the high mass outflow rate scenario (Case A, Ṁ_p = 2.93 M_⊙ yr⁻¹). The different columns of the plot represent the different combinations of R_ph and R_int that we modeled in this work and the different rows represent the three different Δθ (see Sect. 2 for an explanation of the choice of those values). Each subplot shows the degree of the polarization P as a function of the 21 viewing angles Θ, equally spaced in cosine (ΔcosΘ = 0.1) between a north-polar (cosΘ = 1, face-on) and a south-polar (cosΘ = −1, face-on) orientation. We find that this configuration results in polarization levels below one (P < 1%) for all viewing angles and for 10/12 simulations (P < 0.5%).
