Data for paper "Nonlinear Evolution of the Unstratified Polydisperse Dust Settling Instability"

Data and plotting scripts used for paper "Nonlinear Evolution of the Unstratified Polydisperse Dust Settling Instability" Aly &amp; Paardekooper 2025, Astronomy &amp; Astrophysics.<br>The Dust Settling Instability is thought to be triggered at the early stages of disc formation, and may play a role in planet formation. Here we numerically investigate its non-linear growth rate, paying close attention to the effects of spatial resolution and whether the dust consists of one or multiple species with different sizes.<br>The paper uses numerical hydrodynamics algorithms (Idefix and Fargo3D) to simulate the Dust Settling Instability in a local shearing box. The data (snapshots and time evolution tables), along with the plotting scripts are provided here.<br>

本数据集为论文《非分层多分散尘埃沉降不稳定性的非线性演化》（Nonlinear Evolution of the Unstratified Polydisperse Dust Settling Instability，Aly & Paardekooper，2025，《Astronomy & Astrophysics》）所用的数据与绘图脚本。尘埃沉降不稳定性（Dust Settling Instability）被认为在行星盘形成的早期阶段触发，并可能在行星形成过程中发挥作用。本研究通过数值模拟手段探究其非线性增长速率，重点关注空间分辨率的影响，以及尘埃是由单一粒径颗粒还是多种不同粒径颗粒构成。该论文采用数值流体力学算法（Idefix 与 Fargo3D），在局地剪切盒中模拟尘埃沉降不稳定性。本数据集提供了相关数据（含数据快照与时间演化数据表）以及绘图脚本。
