| description | 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 (Rp ∼ 0.6–2.0R⊕) and orbit stars of various magnitudes
(Ks = 5.78–10.78, V = 8.4–15.69) and effective temperatures (Teff ∼ 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 Rp < 2 R⊕. |
