The field substellar mass function based on the full-sky 20 pc census of 525 L, T, and Y dwarfs
JD Kirkpatrick, CR Gelino, JK Faherty… - The Astrophysical …, 2021 - iopscience.iop.org
We present final Spitzer trigonometric parallaxes for 361 L, T, and Y dwarfs. We combine
these with prior studies to build a list of 525 known L, T, and Y dwarfs within 20 pc of the …

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 …
