Data from "Gas-Dust Interplay in White Dwarf Debris Discs with Multi-Fluid Smoothed Particle Hydrodynamics"

The paper by Martinez-Brunner et al. (2026) simulates multi-fluid 3D smoothed particle hydrodynamics (SPH) simulations of debris discs aroundwhite dwarfs, studying gas-dust interactions self-consistently for the first time. We used Phantom SPH (Price et al. 2018) for the hydrodynamic models and MCFOST (Pinte et al. 2006, 2009) to get Spectral energy distributions of the final state of the models. The codes used to perform the simulations are available at Phantom -- https://github.com/danieljprice/phantom MCFOST -- https://github.com/cpinte/mcfost The dataset contains the following data to recreate any of the figures: Snapshots used to create Figures 1, 2, 3, and 5. Post-processed data to recreate Figure 4. .fits.gz files of the SED created by post-processing the simulation snapshots with MCFOST for recreating Figures 6 and 7. The data to recreate any figure in the paper are in Figure*.zip. Each file uses the same name as the legend entry in the respective figure. To recreate any simulation in the paper, all required files are in Simulations.zip. There are multiple subdirectories of different models with these files inside: .setup: The file used by phantomsetup to create the initial conditions of the disc. .in: The file used by Phantom to perform the simulation. .para: A file containing the parameters used by MCFOST to perform the Radiative Transfer calculations. initial snapshot first .ev file first .log file The files are named either mwdddDD or mwdddGO, depending on whether they are multi-fluid (Dusty Disc) or single-fluid (Gas Only). The binary code snapshots containing the raw data (particle positions, velocities, thermal energy, etc.) can be visualised by Splash (Price 2007) or Sarracen (Harris & Tricco 2023). The latter was used to create the figures in the paper.
