摘要
Over a dozen T dwarfs, brown dwarfs that exhibit methane absorption features at 1.6 and 2.2 , have been discovered by the 2MASS survey. We discuss how the search for these objects has been made, point out some of the limitations of using near-infrared data to find the warmest T dwarfs, and highlight a few of the more interesting T dwarfs that have been identified in 2MASS data.
