Decaying Turbulence in Molecular Clouds

<strong>Introduction</strong> This data release contains a suite of 15 AREPO simulations of a spherical molecular clouds of mass \(M=10^4\text{M}_\odot\) and radius \(R \approx 9\text{pc}\) seeded with different types of decaying turbulence. The initial conditions for each simulation are different, with different turbulent modes: mixed turbulence, purely compressive, and purely solenoidal; and different Virial ratios: gravitationally underbound and overbound clouds. <strong>Simulations</strong> Each of the .zip archives contains a simulation. The simulation name is as follows: <em>&lt;Turbulent mode&gt;&lt;RNG seed&gt;&lt;Virial ratio&gt;</em> where: Turbulent mode can be: M = mixed, C = compressive, S = solenoidal. RNG seed used to generate the turbulence can be: 26, 57 and 90. The Virial ratio can be: <em>none</em> = Virial equilibrium (\(\alpha_\text{vir}=1.0 \)), O = overbound (\(\alpha_\text{vir}=0.6\)), U = underbound (\(\alpha_\text{vir}=2.0\)). Each simulation consists of: Four simulation snapshots, which are AREPO binary files, corresponding to the four epochs of interest: when total mass in sinks/stars is \(250\text{M}_\odot\), \(500\text{M}_\odot\), \(750\text{M}_\odot\), \(1000\text{M}_\odot\). Four density grids, corresponding to the four snapshots, which are ray-casted from the AREPO simulations. Four filament networks identified in the density grids using the tool DisPerSE. <strong>Reading in the files</strong> The simulations are easily read and analyzed using the code released as part of our study, called \(\texttt{fiesta}\): fiesta-astro.readthedocs.io. <strong>Supplementary content</strong> The data release also contains two animations: 2D_temporal_animation.mp4 and 3D_sinkepoch_animation.mp4, which are useful for visualizing the simulations.
