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 …

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 …
