Extended Data Fig. 6: The correlation between ΓR and α is not an artefact of thermophysical modelling.
From: Fine-regolith production on asteroids controlled by rock porosity
We fit model radiances emitted by a single triangular facet with zero roughness; if the thermal inertia Γ ≤ Γc = 100 Jm−2K−1s−0.5, then α = 100%, and if Γc<Γ<2,500 Jm−2K−1s−0.5, then α = 0%. We retrieve the expected step function of α as a function of Γ, indicating that the correlation in Fig. 1 is unlikely to be an artefact of the model. The error bars correspond to 1 standard deviation computed on ~ 1.76 × 104 samples on average (Methods).
