摘要
超冷矮星数量丰富、寿命长，并且独特地适于借助 JWST 实现对凌星类地伴星的大气研究。其中最为突出的是 M8.5V 型恒星 TRAPPIST-1 及其七颗行星。尽管 JWST 第一轮观测已开始对行星给出初步认识，但也揭示出它们的大气探索需要对其宿主恒星有更好的理解。在此，我们提出一条以高效且稳健方式表征 TRAPPIST-1 系统——以及其他类似系统——的路线图。我们特别建议：尽管调度更具挑战性，应优先安排多凌星窗口，以减轻恒星活动的影响，并在每花费的 JWST 小时内收集多达两倍的凌星事件。我们得出结论：对于此类系统，行星无法由小型项目孤立研究，而是需要大规模、空间与地面联合的举措，以充分发掘 JWST 在类地行星探索中的能力。
