詹姆斯·韦伯太空望远镜将能够通过发射光谱探测炎热的类地行星的大气层和表面性质。我们确定了凌日系外行星调查卫星(TESS)探测到的18个潜在的类地行星，它们将成为这些观测的理想目标。这些候选行星覆盖了广泛的行星半径(Rp∼0.6-2.0R⊕)和不同星等(K S=5.78-10.78，V=8.4-15.69)和有效温度(T ef∼3000-6000K)的轨道恒星。我们使用TESS后续观测计划收集的地面观测数据和两个审查工具--戴夫和三角龙--来评估这些候选行星作为行星的可靠性。我们验证了13颗行星：TOI-206b、TOI-500b、TOI-544b、TOI-833b、TOI-1075b、TOI-1411b、TOI-1442b、TOI-1693b、TOI-1860b、TOI-2260b、TOI-2411b、TOI-2427b和TOI-2445b。其中7颗行星(TOI-206b、TOI-500b、TOI-1075b、TOI-1442b、TOI-2260b、TOI-2411和TOI-2445b)是超短周期行星。TOI-1860是迄今为止最年轻的(133±26 Myr)太阳双胞胎行星。TOI-2260是一颗年轻的(321±96Myr)G矮星，是拥有超短周期行星的最富金属([Fe/H]=0.22±0.06Dex)恒星之一。TOI-2260b的平衡温度估计为∼2600K，也是已知的第四个最热的行星，具有Rp&lt；2R⊕。
The James Webb Space Telescope will be able to probe the atmospheres and surface properties of hot, terrestrial planets via emission spectroscopy. We identify 18 potentially terrestrial planet candidates detected by the Transiting Exoplanet Survey Satellite (TESS) that would make ideal targets for these observations. These planet candidates cover a broad range of planet radii (R p ∼ 0.6–2.0R ⊕) and orbit stars of various magnitudes (K s = 5.78–10.78, V = 8.4–15.69) and effective temperatures (T eff ∼ 3000–6000 K). We use ground-based observations collected through the TESS Follow-up Observing Program (TFOP) and two vetting tools—DAVE and TRICERATOPS—to assess the reliabilities of these candidates as planets. We validate 13 planets: 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, and TOI-2445 b. Seven of these planets (TOI-206 b, TOI-500 b, TOI-1075 b, TOI-1442 b, TOI-2260 b, TOI-2411 b, and TOI-2445 b) are ultra-short-period planets. TOI-1860 is the youngest (133 ± 26 Myr) solar twin with a known planet to date. TOI-2260 is a young (321 ± 96 Myr) G dwarf that is among the most metal-rich ([Fe/H] = 0.22 ± 0.06 dex) stars to host an ultra-short-period planet. With an estimated equilibrium temperature of ∼2600 K, TOI-2260 b is also the fourth hottest known planet with R p < 2 R ⊕.
