AI 中文摘要
为支持下一代宜居行星搜索与表征任务的开发,需要高保真的天体物理与仪器噪声模拟工具。本文介绍pyEDITH,这是一款基于Python的日冕仪曝光时间计算器,专为NASA下一个推荐旗舰任务——宜居世界望远镜(Habitable Worlds Observatory, HWO)打造,该望远镜的任务是在数十个邻近系外行星系统中搜索宜居性与生命迹象。pyEDITH设计用于模拟HWO直接成像观测中与波长相关的曝光时间和信噪比(S/N),同时考虑实际工程规格与用户自定义的目标信息。其模块化架构可在任务需求演变时保持灵活性,能与现代天文工作流无缝集成,旨在供不同技能水平的科研人员使用,以了解不同HWO架构在系外行星分析中的能力与局限。该代码已通过现有曝光时间计算器验证,以开源形式发布在GitHub与Zenodo上,还可通过图形用户界面访问。pyEDITH软件包包含API文档、教程笔记本,已用于即将发表的科学出版物。
英文摘要
To support the development of next-generation missions for the search and characterization of habitable planets, high-fidelity tools for astrophysical and instrumental noise simulations are needed. In this paper, we introduce pyEDITH, the Python-based coronagraphic exposure time calculator built for the next recommended NASA flagship mission, the Habitable Worlds Observatory (HWO), tasked with searching for signs of habitability and life in dozens of nearby exoplanet systems. pyEDITH is designed to simulate wavelength-dependent exposure times and signal-to-noise ratios (S/N) for synthetic HWO direct imaging observations, considering realistic engineering specifications and user-defined target information. Its modular architecture ensures flexibility as mission requirements evolve. pyEDITH enables a streamlined integration with modern astronomical workflows and was designed to be used by the scientific community at all skill levels for understanding the capabilities and limitations of different HWO architectures for exoplanet analyses. The code has been validated against existing exposure time calculators and released open-source on GitHub and Zenodo, as well as made accessible through a Graphical User Interface. The pyEDITH package includes API documentation, tutorial notebooks, and has been used in forthcoming scientific publications.
