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 …

Temperate Earth-sized planets transiting a nearby ultracool dwarf star
Star-like objects with effective temperatures of less than 2,700 kelvin are referred to as
'ultracool dwarfs'. This heterogeneous group includes stars of extremely low mass as well as …

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 rotation and galactic kinematics of mid M dwarfs in the solar neighborhood
ER Newton, J Irwin, D Charbonneau… - The Astrophysical …, 2016 - iopscience.iop.org
Rotation is a directly observable stellar property, and it drives magnetic field generation and
activity through a magnetic dynamo. Main-sequence stars with masses below approximately …

Population properties of brown dwarf analogs to exoplanets
We present a kinematic analysis of 152 low surface gravity M7-L8 dwarfs by adding 18 new
parallaxes (including 10 for comparative field objects), 38 new radial velocities, and 19 new …

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 …
