论文摘要
Many processes during the evolution of protoplanetary disks and during planet formation are highly sensitive to the sizes of dust particles that are present in the disk: The efficiency of dust accretion in the disk and volatile transport on dust particles, gravoturbulent instabilities leading to the formation of planetesimals, or the accretion of pebbles onto large planetary embryos to form giant planets are typical examples of processes that depend on the涉及的灰尘颗粒的尺寸。此外，辐射特性（如吸收或散射不相处）取决于粒径。为了解释原月球磁盘中灰尘的观察结果，需要对灰尘尺寸进行适当的估计。 我们提出Dustpy-一个Python包装，以模拟原月球磁盘中的尘埃演化。 Dustpy解决了气体和尘埃运输，包括粘性对流和扩散以及灰尘颗粒的碰撞生长。 Dustpy的编写是一个模块化的概念，使得模型的每个方面都可以轻松修改或扩展，以提供大量的研究机会。
Many processes during the evolution of protoplanetary disks and during planet formation are highly sensitive to the sizes of dust particles that are present in the disk: The efficiency of dust accretion in the disk and volatile transport on dust particles, gravoturbulent instabilities leading to the formation of planetesimals, or the accretion of pebbles onto large planetary embryos to form giant planets are typical examples of processes that depend on the sizes of the dust particles involved. Furthermore, radiative properties like absorption or scattering opacities depend on the particle sizes. To interpret observations of dust in protoplanetary disks, a proper estimate of the dust particle sizes is needed. We present DustPy - A Python package to simulate dust evolution in protoplanetary disks. DustPy solves gas and dust transport including viscous advection and diffusion as well as collisional growth of dust particles. DustPy is written with a modular concept, such that every aspect of the model can be easily modified or extended to allow for a multitude of research opportunities.
