The Missing Link: Early Methane (“T”) Dwarfs in the Sloan Digital Sky Survey
The Missing Link: Early Methane (“T”) Dwarfs in the Sloan Digital Sky Survey
We report the discovery of three cool brown dwarfs that fall in the effective temperature gap between the latest L dwarfs currently known, with no methane absorption bands in the 1-2.5 µm range, and the previously known methane (T) dwarfs, whose spectra are dominated by methane and water. The newly …
