The Near-Infrared Spectrum of the Brown Dwarf Gliese 229B
The Near-Infrared Spectrum of the Brown Dwarf Gliese 229B
A medium-resolution 1.0-2.5 μm spectrum of the brown dwarf Gliese 229B has been obtained using the facility spectrometer CGS4 on the United Kingdom Infrared Telescope. In addition to the broad spectral structure seen in earlier low-resolution observations, the new spectrum reveals a large number of absorption lines, many of which …
