Ariel 已被选为 ESA 于 2028 年发射的 M4 任务，旨在描述大量多样化的系外行星大气层的特征，以深入了解银河系内的行星形成和演化。在这里，我们介绍了 Ariel 观测当前已知系外行星和预测凌日系外行星勘测卫星 (TESS) 发现的能力的研究。我们使用 Ariel 辐射模型 (ArielRad) 来模拟仪器性能，发现其中约 2000 个行星具有可以通过 Ariel 来表征的大气信号。该潜在行星列表包含各种行星和恒星参数。我们从中选择了一个示例任务参考样本 (MRS)，由 1000 个要在主要任务生命周期内完成的不同行星组成，这与之前的研究一致。我们还探索了对较小行星的大气层进行深入调查的任务能力，这些行星的大气层可能是浓缩的或次要的。地球大小的行星和大气层比 H/He 重的超级地球将更难以用光谱观察。然而，通过研究观测约 110 个地球大小/超级地球所需的时间，我们发现 Ariel 可能具有对较小行星进行深入观测的强大能力。观测到的行星数量和类型之间的权衡将构成选择过程的关键部分，并且随着新的系外行星发现取代预测的探测，这份行星列表将不断发展。 Ariel 目标列表将不断更新，并重新选择 MRS，以确保主要任务期间所研究的行星种群的最大多样性。
Ariel has been selected as ESA’s M4 mission for launch in 2028 and is designed for the characterization of a large and diverse population of exoplanetary atmospheres to provide insights into planetary formation and evolution within our Galaxy. Here we present a study of Ariel’s capability to observe currently known exoplanets and predicted Transiting Exoplanet Survey Satellite (TESS) discoveries. We use the Ariel radiometric model (ArielRad) to simulate the instrument performance and find that ∼2000 of these planets have atmospheric signals which could be characterized by Ariel. This list of potential planets contains a diverse range of planetary and stellar parameters. From these we select an example mission reference sample (MRS), comprised of 1000 diverse planets to be completed within the primary mission life, which is consistent with previous studies. We also explore the mission capability to perform an in-depth survey into the atmospheres of smaller planets, which may be enriched or secondary. Earth-sized planets and super-Earths with atmospheres heavier than H/He will be more challenging to observe spectroscopically. However, by studying the time required to observe ∼110 Earth-sized/super-Earths, we find that Ariel could have substantial capability for providing in-depth observations of smaller planets. Trade-offs between the number and type of planets observed will form a key part of the selection process and this list of planets will continually evolve with new exoplanet discoveries replacing predicted detections. The Ariel target list will be constantly updated and the MRS re-selected to ensure maximum diversity in the population of planets studied during the primary mission life.
