A Revised Density Estimate for the Largest Known Exoplanet, HAT-P-67 b
Low-density ( ρ _p < 0.1 g cm ^−3 ) hot Saturns are expected to quickly (<100 Myr) lose their atmospheres owing to stellar irradiation, explaining their rarity. HAT-P-67 b seems to be an exception, with ρ _p < 0.09 g cm ^−3 and maintaining its atmosphere to well after 1 Gyr. We present a...
