论文摘要
开源裙子蒙特卡洛辐射转移代码已使用15年以上，以模拟各种天体物理系统中辐射和灰尘之间的相互作用。在这项工作中，我们介绍了该代码的第9版，该版本已经过重新设计以支持长期目标。我们邀请有兴趣的读者参与新功能的开发，测试和应用，例如除了灰尘外，除了连续辐射传递外进行线条转移外，还包括燃气介质类型，并通过与磁场对齐的非球形防尘晶粒进行建模。我们描述了为这些扩展和其他分辨率准备代码涉及的主要挑战，包括对波长的全新处理以支持运动学。 Skirt 9适当运行400多个手工制作的功能测试，并成功执行所有相关的基准测试。源代码和所有文档均可公开使用，并准备好进行进一步的协作开发。
The open source SKIRT Monte Carlo radiative transfer code has been used for more than 15 years to model the interaction between radiation and dust in various astrophysical systems. In this work, we present version 9 of the code, which has been substantially redesigned to support long-term objectives. We invite interested readers to participate in the development, testing and application of new features such as including gas media types in addition to dust, performing line transfer in addition to continuum radiation transfer, and modeling polarization by non-spherical dust grains aligned by magnetic fields. We describe the major challenges involved in preparing the code for these and other extensions, as well as their resolution, including a completely new treatment of wavelengths to support kinematics. SKIRT 9 properly runs over 400 handcrafted functional tests and successfully performs all relevant benchmarks. The source code and all documentation is publicly available for use and ready for further collaborative development.
