Discovery of the Binarity of Gliese 229B, and Constraints on the System's Properties
We present two epochs of radial velocities of the first imaged T dwarf Gliese 229 B obtained with Keck/NIRSPEC. The two radial velocities are discrepant with one another and with the radial velocity of the host star, at ≈11 σ significance. This points to the existence of a previously postulated, but...
