The Near‐Infrared and Optical Spectra of Methane Dwarfs and Brown Dwarfs
The Near‐Infrared and Optical Spectra of Methane Dwarfs and Brown Dwarfs
We identify the pressure-broadened red wings of the saturated potassium resonance lines at 7700 Å as the source of anomalous absorption seen in the near-infrared spectra of Gliese 229B and, by extension, of methane dwarfs in general. In broad outline, this conclusion is supported by the 1999 work of Tsuji …
