AI总结:

ASTER通过整合AI代理与领域专用工具,为系外行星大气分析提供统一平台,支持多步骤数据处理和检索任务。

摘要:

系外行星观测的扩展催生了对灵活、易用的工作流需求。传输光谱学已成为探测凌星系外行星大气成分的关键技术。这些数据的分析需要结合档案查询、文献检索、辐射传输模型和贝叶斯检索框架,每项都需专业知识。现代大语言模型使AI代理能通过工具集成、结构化提示和迭代推理协调复杂任务。本文介绍ASTER,一个用于系外行星研究的代理科学工具包。ASTER是协调框架,通过使LLM与集成的领域专用工具交互、工作流规划和管理,将LLM能力带给系外行星社区。目前ASTER整合了从NASA系外行星档案下载行星参数和观测数据集的工具,以及通过TauREx辐射传输模型生成凌星光谱,和通过TauREx完成行星参数贝叶斯检索的工具。除了工具集成,代理还通过提出替代建模方法、报告潜在问题并建议解决方案来辅助用户。我们通过WASP-39b的完整案例研究演示ASTER的工作流,使用档案中的观测数据进行多次检索。代理高效地在数据集之间切换,生成适当的正向模型光谱并执行检索。ASTER提供了一个统一的平台用于系外行星大气特征化。持续的发展和社区贡献将继续扩展ASTER在系外行星研究中的应用范围。

英文摘要:

The expansion of exoplanet observations has created a need for flexible, accessible, and user-friendly workflows. Transmission spectroscopy has become a key technique for probing atmospheric composition of transiting exoplanets. The analyses of these data require the combination of archival queries, literature search, the use of radiative transfer models, and Bayesian retrieval frameworks, each demanding specialized expertise. Modern large language models enable the coordinated execution of complex, multi-step tasks by AI agents with tool integration, structured prompts, and iterative reasoning. In this study we present ASTER, an Agentic Science Toolkit for Exoplanet Research. ASTER is an orchestration framework that brings LLM capability to the exoplanetary community by enabling LLM-driven interaction with integrated domain-specific tools, workflow planning and management, and support for common data analysis tasks. Currently ASTER incorporates tools for downloading planetary parameters and observational datasets from the NASA Exoplanet Archive, as well as the generation of transit spectra from the TauREx radiative transfer model, and the completion of Bayesian retrieval of planetary parameters with TauREx. Beyond tool integration, the agent assists users by proposing alternative modeling approaches, reporting potential issues and suggesting solutions, and interpretations. We demonstrate ASTER's workflow through a complete case study of WASP-39b, performing multiple retrievals using observational data available on the archive. The agent efficiently transitions between datasets, generates appropriate forward model spectra and performs retrievals. ASTER provides a unified platform for the characterization of exoplanet atmospheres. Ongoing development and community contributions will continue expanding ASTER's capabilities toward broader applications in exoplanet research.
