Data for: Tidally Torn (2025)

This dataset contains simulation outputs supporting the results presented in Patel, Quarles, Weinberg & Cuntz (2025), which investigates the long-term tidal evolution and survivability of large moons orbiting Earth-mass planets in the habitable zones of M-dwarf stars. All simulations were performed using the REBOUND N-body integrator (with tides enabled) and explore the outcomes for systems around M0, M2, and M4-type host stars across a range of planetary masses and semimajor axes. 📁 Archive Structure The dataset is divided into three compressed .tar files, one per stellar type: M0.tar M2.tar M4.tar Each archive unpacks into a hierarchical directory structure: <Mstar_type>/ └── Mass[<planet_mass>]/ └── ap[<planet_semimajor_axis>]/ ├── sa[<planet_mass>,<semimajor_axis>]_698.bin # REBOUND simulation archive ├── reb_tide[<planet_mass>,<semimajor_axis>]_698.txt # System evolution parameters └── sim_params[<planet_mass>,<semimajor_axis>]_698.txt # Integration metadata Directory level meaning: Level Example Meaning 1 M0/ Stellar spectral type used in simulation 2 Mass[1.00]/ Assumed planetary mass in Earth masses 3 ap[0.520]/ Initial planetary semimajor axis in AU Files listed below Output products for that simulation configuration 📦 File Contents and Interpretation File Format Description sa[<planet_mass>,<semimajor_axis>]_698.bin REBOUND binary archive Complete simulator snapshot history, readable via rebound.Simulationarchive() reb_tide[<planet_mass>,<semimajor_axis>]_698 ASCII Time evolution of orbital + tidal parameters sim_params[<planet_mass>,<semimajor_axis>]_698 ASCII Simulation runtime settings, step sizes, error metrics Important keyword flag:Both reb_tide and sim_params may contain the value Roche, indicating that the moon either entered the Roche limit or exceeded the dynamical stability limit, which classifies the simulation as unstable / moon lost. 🧩 Data Usage Guidance Users may extract orbital histories directly using REBOUND’s Simulationarchive() function. reb_tide is appropriate for statistical post-processing (e.g., survival time distributions, tidal migration rates). Combined interpretation of reb_tide + sim_params flags is recommended when evaluating numerical convergence or physical termination conditions. 📚 Citation Please cite both the paper and the Zenodo DOI: Patel, S.D., Quarles, B., Weinberg N.N., & Cuntz, M.
