The discovery of large numbers of young low-mass stars and brown dwarfs over the past
decade has made it possible to investigate star formation and early evolution in a previously …

Understanding the dominant brown dwarf and giant planet formation processes, and finding
out whether these processes rely on completely different mechanisms or share common …

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 …

Euclid is a space-based survey mission from the European Space Agency designed to
understand the origin of the Universe's accelerating expansion. It will use cosmological …

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 …

We present ground-based spectroscopic verification of 6 Y dwarfs (see also Cushing et al.),
89 T dwarfs, 8 L dwarfs, and 1 M dwarf identified by the Wide-field Infrared Survey Explorer …

We present the discovery of seven ultracool brown dwarfs identified with the Wide-field
Infrared Survey Explorer (WISE). Near-infrared spectroscopy reveals deep absorption bands …

We present the discovery of another seven Y dwarfs from the Wide-field Infrared Survey
Explorer (WISE). Using these objects, as well as the first six WISE Y dwarf discoveries from …

We present the full results of our decade-long astrometric monitoring programs targeting 31
ultracool binaries with component spectral types M7–T5. Joint analysis of resolved imaging …

Using the integral field spectrograph OSIRIS, on the Keck II telescope, broad near-infrared H-
and K-band spectra of the young exoplanet HR8799b have been obtained. In addition, six …
