Molecular Hydrogen Controls the Temperatures of Flares on TRAPPIST-1

The Astrophysical Journal Letters
Early JWST observations of TRAPPIST-1 have revealed an unexpected puzzle: energetic white-light flares ( E  > 10 ^30 erg) reach temperatures of only ∼3500–4000 K, nearly 3 times cooler than typical solar flares, which peak around 9000–10,000 K.
