HCN and C2H2 in the Atmosphere of a T8.5+T9 Brown Dwarf Binary

HCN and C2H2 in the Atmosphere of a T8.5+T9 Brown Dwarf Binary

T-type brown dwarfs present an opportunity to explore atmospheres teeming with molecules such as H _2 O, CH _4 , and NH _3 , which exhibit a wealth of absorption features in the mid-infrared. With JWST, we can finally explore this chemistry in detail, including for the coldest brown dwarfs that were...
