Extended Data Fig. 3: Posterior distributions of thermochronologic model parameters for a simulated asteroid with no impact reheating.
From: An early giant planet instability recorded in asteroidal meteorites
Each histogram reflects 106 steps of post-burn-in MCMC simulation. Panels correspond to parameters in Table 1: solar system midplane temperature (a) and initial 26Al/27Al (d) and the simulated asteroid’s Ar closure temperature (b), bulk density (c), radius (e), specific heat capacity (f), Al abundance (g), accretion time (h), and thermal conductivity (i). Dashed lines demarcate prior distributions of each corresponding parameter. Posterior distributions of bulk density (c) and initial 26Al/27Al (d) agree well with their priors, while all other parameters appear inconsistent with their respective priors. Extended Data Table 1 reports summary statistics.
