AI总结:

本文介绍ExoMol数据库2024年发布,涵盖91种分子、224种同位素体近10^12条跃迁,新增MARVEL化、紫外扩展、光解离截面及ExoMolHR高分辨率提取工具,服务于系外行星和热大气光谱研究。

摘要:

ExoMol数据库(www.exomol.com)为热大气的光谱研究提供分子数据。这些数据被广泛用于模拟系外行星、冷恒星及其他天文物体的 atmospheres,以及多种 terrestrial 应用。2024年数据发布报告了该数据库的当前状态,其中包含91种分子和224种同位素体的推荐谱线列表,总计近10^12条独立跃迁。数据库的新功能包括:对谱线列表进行广泛的“MARVEL化”处理,使其可用于高分辨率研究;将若干谱线列表扩展到紫外波段;提供光解离截面;以及扩展了展宽参数的提供。部分内部数据规范已用JSON重写,并调整为符合其他国际标准。本文还讨论了数据产品,包括比热容、用于等离子体研究的寿命数据库,以及ExoMolHR网络应用,该应用允许仅提取高分辨率数据。

英文摘要:

The ExoMol database (www.exomol.com) provides molecular data for spectroscopic studies of hot atmospheres. These data are widely used to model atmospheres of exoplanets, cool stars and other astronomical objects, as well as a variety of terrestrial applications. The 2024 data release reports the current status of the database which contains recommended line lists for 91 molecules and 224 isotopologues giving a total of almost 10$^{12}$ individual transitions. New features of the database include extensive "MARVELization" of line lists to allow them to be used for high resolutions studies, extension of several line lists to ultraviolet wavelengths, provision of photodissociation cross sections and extended provision of broadening parameters. Some of the in-house data specifications have been rewritten in JSON and moved to conformity with other international standards. Data products, including specific heats, a database of lifetimes for plasma studies, and the ExoMolHR web app which allows exclusively high resolution data to be extracted, are discussed.
