论文摘要
詹姆斯·韦伯（James Webb）空间望远镜（JWST）将能够通过发射光谱探测热陆地行星的大气和表面特性。我们确定了由过渡系外行星调查卫星（TESS）检测到的18个潜在的陆地行星候选者，这将为这些观察带来理想的目标。 These planet candidates cover a broad range of planet radii ($R_{\rm p} \sim 0.6 - 2.0 R_\oplus$) and orbit stars of various magnitudes ($K_s = 5.78 - 10.78$, $V = 8.4 - 15.69$) and effective temperatures ($T_{\rm eff }\sim 3000 - 6000$ K).我们使用通过TESS随访观测计划（TFOP）和两个审核工具（Dave和Triceratops）收集的基于地面的观察结果来评估这些候选者作为行星的可靠性。我们验证了13个行星：TOI-206 B，TOI-500 B，TOI-544 B，TOI-833 B，TOI-1075 B，TOI-1075 B，TOI-1411 B，TOI-1442 B，TOI-1442 B，TOI-1693 B，TOI-1860 B，TOI-1860 B，TOI-1860 B，TOI-2260 B，TOI-2260 B，TOI-22411 B，TOI-2411 B，TOI-2427 B，TOI-2427 B，TOI-24444444444444444。这些行星中有七个（TOI-206 B，TOI-500 B，TOI-1075 B，TOI-1442 B，TOI-1442 B，TOI-2260 B，TOI-2411 B和TOI-2445 B）是Ultra-Short-Period行星。 TOI-1860是迄今为止已知的星球最小的太阳能双胞胎（$ 133 \ pm 26 $ Myr）。 TOI-2260是年轻的（$ 321 \ pm 96 $ Myr）G矮人，它是最富含金属的（[fe/h] = $ 0.22 \ pm 0.06 $ dex）的星星，可容纳一个超短暂的period星球。估计的平衡温度为$ \ sim 2600 $ K，TOI-2260 B也是第四个最热门的行星，$ r _ {\ rm p} <2 \，r_ \ oplus $。
The James Webb Space Telescope (JWST) will be able to probe the atmospheres and surface properties of hot, terrestrial planets via emission spectroscopy. We identify 18 potentially terrestrial planet candidates detected by the Transiting Exoplanet Survey Satellite (TESS) that would make ideal targets for these observations. These planet candidates cover a broad range of planet radii ($R_{\rm p} \sim 0.6 - 2.0 R_\oplus$) and orbit stars of various magnitudes ($K_s = 5.78 - 10.78$, $V = 8.4 - 15.69$) and effective temperatures ($T_{\rm eff }\sim 3000 - 6000$ 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 ($133 \pm 26$ Myr) solar twin with a known planet to date. TOI-2260 is a young ($321 \pm 96$ Myr) G dwarf that is among the most metal-rich ([Fe/H] = $0.22 \pm 0.06$ dex) stars to host an ultra-short-period planet. With an estimated equilibrium temperature of $\sim 2600$ K, TOI-2260 b is also the fourth hottest known planet with $R_{\rm p} < 2 \, R_\oplus$.
