Supervirial Simulations

20 supervirial (region is expanding) simulations of 1000 stars with an initial fractal dimension of 1.6, meaning the initial distribution of stars is clumpy.
Originally used in Blaylock-Squibbs & Parker (2024) 'The dynamical evolution of star-forming regions measured with INDICATE'.
The simulations are run using the <em>kira</em> integrator which is part of <em>starlab</em>: https://www.sns.ias.edu/~starlab/index.html
The simulations are purely dynamical with no stellar evolution. We do not simulate the gas potential the stars would be embedded in, nor do we simulate the galactic tidal field. The simulations show 10 Myr of purely dynamic evolution.

本数据集包含20组超维里（supervirial，区域处于膨胀状态）模拟，每组模拟包含1000颗恒星，其初始分形维数为1.6，即恒星初始分布呈团簇形态。该数据集最初用于Blaylock-Squibbs与Parker（2024）发表的论文《利用INDICATE量化恒星形成区域的动力学演化》。本次模拟采用隶属于starlab的kira积分器运行，相关资源可访问：https://www.sns.ias.edu/~starlab/index.html。本模拟仅涉及纯动力学过程，未纳入任何恒星演化环节；我们既未模拟恒星所嵌入的气体势场，也未考虑银河系潮汐场的影响。该模拟展示了时长为10 Myr（百万年）的纯动力学演化历程。
