We present the direct-imaging discovery of a substellar companion (a massive planet or low-
mass brown dwarf) to the young, γ Doradus (γ Dor)-type variable star HIP 39017 (HD …

Owing to their similarities with giant exoplanets, brown dwarf companions of stars provide
insights into the fundamental processes of planet formation and evolution. From their orbits …

Tension remains between the observed and modeled properties of substellar objects, but
objects in binary orbits, with known dynamical masses, can provide a way forward. HD …

ABSTRACT We present the Ultracool Dwarf Companion Catalogue of 278 multiple systems,
32 of which are newly discovered, each with at least one spectroscopically confirmed …

We present follow-up SCExAO/CHARIS H-and K-band (R∼ 70) high-contrast integral field
spectroscopy and Keck/NIRC2 photometry of directly imaged brown dwarf companion HD …

Astrometry and Precise Radial Velocities Yield a Complete Orbital Solution for the Nearby
Eccentric Brown Dwarf LHS 1610 b - IOPscience Skip to content IOP Science home …

We present the joint astrometric and direct imaging discovery, mass measurement, and
orbital analysis of HD 63754 B (HIP 38216 B), a companion near the stellar-substellar …

Context. A low-mass companion potentially in the brown dwarf mass regime was discovered
on a~ 12 yr orbit (~ 5.5 au) around HD 167665 using radial velocity (RV) monitoring. Joint …

Brown dwarfs with measured dynamical masses and spectra from direct imaging are
benchmarks that anchor substellar atmosphere cooling and evolution models. We present …

Brown dwarfs (BDs) are model degenerate in age and mass. High-contrast imaging and
spectroscopy of BD companions to host stars where the mass and age can be …
