The First Brown Dwarf Results from the Wide-field Infrared Survey Explorer (WISE) (Christopher R. Gelino, Infrared Processing and Analysis Center/California Institute of Technology)

The Wide-field Infrared Survey Explorer (WISE) has surveyed the entire sky at 4 different wavelengths. The two shortest bands (W1 at 3.4 microns and W2 at 4.6 microns) were specifically designed to probe a deep methane feature at 3.3 microns and a region relatively free of opacity at 4.6 microns in the atmospheres of brown dwarfs. The resulting very red W1-W2 color helps to highlight cool brown dwarfs against other astronomical objects, thus making the identification of candidate brown dwarfs much easier. Here I report the first results of our searches for the coolest brown dwarfs, including the discovery of a new spectral class of brown dwarfs: the Y dwarfs.
