The Hawaii infrared parallax program. I. Ultracool binaries and the L/T transition

TJ Dupuy, MC Liu - The Astrophysical Journal Supplement …, 2012 - iopscience.iop.org
We present the first results from our high-precision infrared (IR) astrometry program at the
Canada–France–Hawaii Telescope. We measure parallaxes for 83 ultracool dwarfs …

The Hawaii infrared parallax program. II. Young ultracool field dwarfs

MC Liu, TJ Dupuy, KN Allers - The Astrophysical Journal, 2016 - iopscience.iop.org
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 …
