摘要
我们确认了 TESS 发现的两颗气态巨行星的行星性质，它们凌星于具有宽间距恒星伴星的 M 矮星。TOI-3984 A（）是一颗 M4 矮星，宿主一颗短周期（ 天）气态巨行星（ 且 ），并有一颗宽间距白矮星伴星。TOI-5293 A（）是一颗 M3 矮星，宿主一颗短周期（ 天）气态巨行星（ 且 ），并有一颗宽间距 M 矮星伴星。我们使用地基与天基测光、散斑成像以及来自宜居带行星探测器和 NEID 光谱仪的高精度视向速度联合刻画了两个系统。TOI-3984 A b（ K 且 ）与 TOI-5293 A b（ K 且 ）是环绕 M 矮星的热木星尺寸气态行星族中两颗最冷的气体巨行星，并且是温带气态巨行星大气刻画与探测系统架构和迁移情形的三维倾角测量的有利目标。
