Fundamental parameters and spectral energy distributions of young and field age objects with masses spanning the stellar to planetary regime
We combine optical, near-infrared, and mid-infrared spectra and photometry to construct
expanded spectral energy distributions for 145 field age (> 500 Myr) and 53 young (lower …

The Hawaii infrared parallax program. II. Young ultracool field dwarfs
We present a large, uniform analysis of young (≈ 10–150 Myr) ultracool dwarfs, based on
new high-precision infrared (IR) parallaxes for 68 objects. We find that low-gravity (vl-g) late …
