A full-sky census of brown dwarfs within 20pc
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 20pc of... -
Beyond the local volume. I. HST ultracool dwarfs
Ultracool dwarf stars and brown dwarfs provide a unique probe of large-scale Galactic structure and evolution; however, until recently spectroscopic samples of sufficient size,... -
Analysis of the NIR spectra of neighboring L dwarfs
Discrepancies between competing optical and near-infrared (NIR) spectral typing systems for L dwarfs have motivated us to search for a classification scheme that ties the... -
Ultracool SpeXtroscopic survey. I. M7-L5 sample
We present a volume-limited, spectroscopically verified sample of M7-L5 ultracool dwarfs (UCDs) within 25pc. The sample contains 410 sources, of which 93% have trigonometric...
