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 …

Direct imaging of a cold Jovian exoplanet in orbit around the Sun-like star GJ 504
Several exoplanets have recently been imaged at wide separations of> 10 AU from their
parent stars. These span a limited range of ages (< 50 Myr) and atmospheric properties, with …

Precise Dynamical Masses of Directly Imaged Companions from Relative Astrometry, Radial Velocities, and Hipparcos–Gaia DR2 Accelerations
TD Brandt, TJ Dupuy, BP Bowler - The Astronomical Journal, 2019 - iopscience.iop.org
We measure dynamical masses for five objects—three ultracool dwarfs, one low-mass star,
and one white dwarf—by fitting orbits to a combination of the Hipparcos–Gaia Catalog of …
