论文摘要
我们描述了一个新模块的实现,该模块可用于模拟粒子运动受随机力影响的物理系统。预计此类力将存在于湍流的杂质磁盘或残留的行星磁盘中。我们的实现提供了一种方便的方式,可以与每个粒子的用户指定振幅和自动相关时间生成相关噪声。该模块的内存要求最少,并且在Reboundx附加效果库中可免费使用。
We describe the implementation of a new module which can be used to simulate physical systems in which the motion of particles is affected by stochastic forces. Such forces are expected to be present in turbulent circumstellar disks or remnant planetesimal disks. Our implementation offers a convenient way to generate correlated noise with a user-specified amplitude and auto-correlation time for each particle. The module has minimal memory requirements and is freely available within the REBOUNDx additional effects library.
