The Astrophysical Journal Letters, 2023 Cold, substellar objects such as brown dwarfs have long been recognized as contaminants in color-selected samples of active galactic nuclei (AGNs). In particular, their near- to mid-infrared colors (1–5 μ m) can closely resemble the V-shaped ( f _λ ...

Substellar Companions to Main Sequence Stars: No Brown Dwarf Desert at Wide Separations
, 2001 We use three field L and T dwarfs which were discovered to be wide companions to known stars by the Two Micron All-Sky Survey (2MASS) to derive a preliminary brown dwarf companion frequency.

Young Brown Dwarfs as Giant Exoplanet Analogs [PDF]
, 2013 Young brown dwarfs and directly-imaged exoplanets have enticingly similar photometric and spectroscopic characteristics, indicating that their cool, low gravity atmospheres should be studied in concert.

Conflict Resolution Quarterly, EarlyView.ABSTRACT This article examines the role of restorative justice coordinators in supporting teachers and schools in adopting a whole‐school approach to restorative justice in education. Coordinators are often tasked with implementing a train‐and‐hope model, in which they receive initial training in restorative justice but are largely left unsupported ...

The Initial Mass Function Based on the Full-sky 20 pc Census of ∼3600 Stars and Brown Dwarfs
The Astrophysical Journal Supplement SeriesA complete accounting of nearby objects—from the highest-mass white dwarf progenitors down to low-mass brown dwarfs—is now possible, thanks to an almost complete set of trigonometric parallax determinations from Gaia, ground-based surveys, and Spitzer ...
