The James Webb Space Telescope NIRSpec-PRISM Transmission Spectrum of the Super-puff, Kepler-51d

Kepler-51 is a 500 Myr G dwarf hosting three “super-puffs” and one low-mass nontransiting planet. Kepler-51d, the coolest ( T _eq ∼ 350 K) transiting planet in this system is also one of the lowest-density super-puffs known to date ( ρ _p = 0.038 ± 0.009 g cm ^−3 ). With a planetary mass of M _p = 5...
