摘要:

H $_3^+$是一种普遍存在的重要天体物质,其光谱在星际介质、行星和超新星SN 1897 a的遗迹中都有观测到。它作为冷却器的作用对于气体巨行星和系外行星,甚至可能是早期宇宙都很重要。这使得H $_3^+$的光谱性质、冷却函数和配分函数成为天文模型和分析的关键参数。作为ExoMol项目的一部分,计算了一个新的高精度,非常广泛的H $_3^+$的线列表,称为MiZATeP,以及温度依赖性冷却函数和配分函数以及%单个激发态的寿命。这些数据以电子形式提供,作为本文的补充数据,网址为http://www.exomol.com

英文摘要:

H$_3^+$ is a ubiquitous and important astronomical species whose spectrum has been observed in the interstellar medium, planets and tentatively in the remnants of supernova SN1897a. Its role as a cooler is important for gas giant planets and exoplanets, and possibly the early Universe. All this makes the spectral properties, cooling function and partition function of H$_3^+$ key parameters for astronomical models and analysis. A new high-accuracy, very extensive line list for H$_3^+$ called MiZATeP was computed as part of the ExoMol project alongside a temperature-dependent cooling function and partition function as well as lifetimes for %individual excited states. These data are made available in electronic form as supplementary data to this article and at http://www.exomol.com
