摘要
詹姆斯·韦伯空间望远镜（JWST）将能够通过发射光谱探测炽热类地行星的大气与表面性质。我们识别出18颗由凌星系外行星巡天卫星（TESS）发现的潜在类地行星候选体，它们将是此类观测的理想目标。这些行星候选体涵盖广泛的行星半径范围（），并环绕不同星等的恒星（，）以及有效温度（ K）的恒星运行。我们利用通过TESS后续观测计划（TFOP）收集的地面观测以及两种筛选工具——DAVE和TRICERATOPS——来评估这些候选体作为行星的可靠性。我们确认了13颗行星：TOI-206 b、TOI-500 b、TOI-544 b、TOI-833 b、TOI-1075 b、TOI-1411 b、TOI-1442 b、TOI-1693 b、TOI-1860 b、TOI-2260 b、TOI-2411 b、TOI-2427 b和TOI-2445 b。其中7颗行星（TOI-206 b、TOI-500 b、TOI-1075 b、TOI-1442 b、TOI-2260 b、TOI-2411 b和TOI-2445 b）为超短周期行星。TOI-1860是迄今已知拥有行星的最年轻（ Myr）太阳孪生恒星。TOI-2260是一颗年轻的（ Myr）G型矮星，也是宿主超短周期行星的恒星中金属丰度最高（[Fe/H] = dex）者之一。TOI-2260 b的平衡温度估计约为2600 K，也是已知半径的第四炽热行星。
