Cascading Habitability

Dataset supporting research article "A Peek at the Role of Disruptive Impacts on Ocean Generation and Longevity in Icy Moons": IcyDwarf_v24.7.2 used to obtain the data (also available from https://github.com/MarcNeveu/IcyDwarf) README.md indicates how to interpret output files in Cascading_Habitability_Data folder (see below). In Cascading_Habitability_Data folder: 1 Pre-impact conditions for SPH: IcyDwarf pre-impact simulations to obtain initial temperature profile and state of differentiation to initialize SPH simulations (Outputs80Kdry run was used) 2 SPH: Gadget2 users' guide (Springel, 2005) explaining how to interpret files (see its section 6); plus 4 folders, one per simulation, containing: Initial and final simulation snapshots (i.e., input and output) Binned thermal-compositional profiles provided back to IcyDwarf thermal evolution model For two of the simulations, thermal profiles adjusted for entropy correction (see Supplementary Section 6). 3 Post-impact main text: IcyDwarf no-impact (New* folders) and post-impact simulations (Post* folders), including zooms on the first 10 Myr post-reaccretion (First 10 Myr post-reaccr folder) SPH output processing* .xslx: Excel spreadsheets with step-by-step (tab by tab) conversions of SPH outputs into IcyDwarf post-impact inputs Orbit change upon impact.xslx: Excel spreadsheet with calculation of upper bounds on change in semi-major axis and eccentricity upon impact. 4 Suppl sims: Simulations supporting supplementary material: AccrT* folders: Non-uniform accretional profiles (Supplementary Section 1) Pre* folders: Progenitor thermal evolution for Outputs80Kdry case (see 1 Pre-impact conditions for SPH folder) run for 4.5 Gyr (Supplementary Section 3) *cooler folders: Post-impact simulations started with cooler entropy-corrected SPH profile (Supplementary Section 6) *80Ksurf folders: Post-impact simulations with an 80-K surface temperature (Supplementary Section 7) *50Gyr folder: Post-impact simulation with a radionuclide content corresponding to 50 Gyr of decay (Supplementary Section 8) Ammonia folder: Simulations of the radius 421 km moon with 2% ammonia (Supplementary Section 9) New* folders: Low-spatial-resolution simulations of a moon with starting uniform composition and arbitrarily high uniform temperature (Supplementary Section 10).
