Predicted flux density of dust emission from the CPD of PDS 70 c when the planet mass and gas accretion rate are M_pl = (0.5–20) M_J and ${\dot{M}}_{\mathrm{g},\mathrm{p}\mathrm{l}}=({10}^{-9}-{10}^{-6.5})$ M_J yr⁻¹. The purple circles represent the plausible planet properties: $M_{\mathrm{p}\mathrm{l}}=10M_{\mathrm{J}}\text{ and }{\dot{M}}_{\mathrm{g},\mathrm{p}\mathrm{l}}=2\times {10}^{-7}{M}_{\mathrm{J}}{\mathrm{y}\mathrm{r}}^{-1}$ (Left) The strength of turbulence and the dust-to-gas mass ratio in the inflow are fixed as α = 10⁻⁴ and x = 0.01, respectively. The red solid and dashed curves represent the planet property range reproducing the observed value, 86 ± 16 μJy (Benisty et al. 2021). The black curves and lines represent the previous estimates of the properties listed in Table 2. (Right) The red, brown, green, and orange shaded regions represent the planet property ranges reproducing the observed value with (α, x) = (10⁻⁴, 0.01), (10⁻⁵, 0.01), (10⁻³, 0.01), and (10⁻⁴, 0.001), respectively. The solid purple curve is the obtained constraint on MMdot: $M_{\mathrm{p}\mathrm{l}}{\dot{M}}_{\mathrm{g},\mathrm{p}\mathrm{l}}\ge 4\times {10}^{-7}{M}_{\mathrm{J}}^2{\mathrm{y}\mathrm{r}}^{-1}$. The vertical and horizontal dashed purple lines represent the obtained constraints on the planet mass and the gas accretion rate, M_pl ≥ 5 M_J and ${\dot{M}}_{\mathrm{g},\mathrm{p}\mathrm{l}}\ge 2\times {10}^{-8}{M}_{\mathrm{J}}{\mathrm{y}\mathrm{r}}^{-1}$ respectively.
