Data for "Carbonaceous Chondrites provide evidence for late-stage planetesimal formation in a pressure bump"

This dataset was produced to simulate the formation of Carbonaceous Chondrite parent bodies using dust evolution models. We track the dust evolution with a Monte Carlo code, accounting for coagulation and fragmentation within a dust trap formed in the outer regions of a planetary gap. Dataset Description: disk_data: Contains output from a 1D gas disk evolution simulation, which includes disk formation, planetary gap opening, and photoevaporation processes. A README file is included in the directory for further details. File types: .dat, .info zerod_data_reduced: Processed output from a zero-dimensional simulation resolving collisions within a multi-component dust population. This dataset is used in Figure 3 of the main manuscript and includes particle sizes and their compositions (i.e., rigid mass fraction). File type: .h5 global_data_reduced: Processed output from a global disk simulation, used to compute the evolution of material delivered to the dust trap. This dataset is used in Figure 4 of the main manuscript and includes radial positions and particle compositions. File type: .h5 feeding_data: Output from the global simulation required as input for local simulations. This file remains unprocessed and contains all particle attributes. File type: .h5 local_data_reduced: Processed output from a local disk simulation. This directory also includes data on planetesimals (formation time and composition). It is used in Figures 4, 5, and 6 of the main manuscript, and includes particle radial positions, Stokes numbers, and compositions. File type: .h5 local_topheavy_data_reduced: Processed output from a local disk simulation. This directory also includes data on planetesimals (formation time and composition). It is used in Figure 2 in the Supplementary material, and includes particle radial positions, Stokes numbers, and compositions.
