The theory of brown dwarfs and extrasolar giant planets
A Burrows, WB Hubbard, JI Lunine, J Liebert - Reviews of Modern Physics, 2001 - APS
Straddling the traditional realms of the planets and the stars, objects below the edge of the
main sequence have such unique properties, and are being discovered in such quantities …

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 …

An infrared spectroscopic sequence of M, L, and T dwarfs
MC Cushing, JT Rayner, WD Vacca - The Astrophysical Journal, 2005 - iopscience.iop.org
Abstract We present a 0.6-4.1 μm spectroscopic sequence of M, L, and T dwarfs. The spectra
have R≡ λ/Δλ≈ 2000 from 0.9 to 2.4 μm and R= 2500-200 from 2.9 to 4.1 μm. These new …
