Validation of 13 Hot and Potentially Terrestrial TESS Planets

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 planet candidates detected by Transiting Exoplanet Survey Satellite (TESS) that would make ideal targets for these observations. These cover a broad range radii ($R_{\rm p} \sim 0.6 - 2.0 R_\oplus$) orbit stars various magnitudes ($K_s = 5.78 10.78$, $V 8.4 15.69$) effective temperatures ($T_{\rm eff }\sim 3000 6000$ K). use ground-based observations collected through TESS Follow-up Observing Program (TFOP) two vetting tools -- DAVE TRICERATOPS assess reliabilities as planets. validate 13 planets: TOI-206 b, TOI-500 TOI-544 TOI-833 TOI-1075 TOI-1411 TOI-1442 TOI-1693 TOI-1860 TOI-2260 TOI-2411 TOI-2427 TOI-2445 b. Seven (TOI-206 b) are ultra-short-period is youngest ($133 \pm 26$ Myr) solar twin with known date. young ($321 96$ G dwarf among most metal-rich ([Fe/H] $0.22 0.06$ dex) host an planet. With estimated equilibrium temperature $\sim 2600$ K, b also fourth hottest $R_{\rm < 2 \, R_\oplus$.
