Keck NIRES Spectral Standards for L, T, and Y Dwarfs
Abstract
We present medium-resolution (λ/Δλ = 2700), near-infrared spectral standards for field L0-L2, L4, and L7-Y0 dwarfs obtained with the Near-Infrared Echellette Spectrometer on the Keck II 10 m telescope. These standards allow for detailed spectral comparative analysis of cold brown dwarfs discovered through ongoing ground-based projects such as Backyard Worlds: Planet 9, and forthcoming space-based spectral surveys such as the James Webb Space Telescope, SPHEREx, Euclid, and the Nancy Grace Roman Space Telescope.
