Protosolar D-to-H Abundance and One Part per Billion PH3 in the Coldest Brown Dwarf

Protosolar D-to-H Abundance and One Part per Billion PH3 in the Coldest Brown Dwarf

The coldest Y spectral type brown dwarfs are similar in mass and temperature to cool and warm (∼200–400 K) giant exoplanets. We can therefore use their atmospheres as proxies for planetary atmospheres, testing our understanding of physics and chemistry for these complex, cool worlds. At these cold t...
