Molecular Hydrogen Controls The Temperatures Of Flares On TRAPPIST-1 - Astrobiology

Summary by astrobiology.com
Early JWST observations of TRAPPIST-1 have revealed an unexpected puzzle: energetic white-light flares (E>1030 erg) reach temperatures of only ∼3500–4000,K, nearly three times cooler than typical solar flares, which peak around 9000–10000,K. Here we explain this difference by identifying the physical mechanism that regulates flare temperatures on late M-dwarfs. The key factor is that in […] The post Molecular Hydrogen Controls The Temperatures O…
