Title: The Brown Dwarf Kinematics Project: Disentangling How Dust and Age Effect Brown Dwarf and Exoplanet Data
Abstract:
The distances and kinematics of brown dwarfs provide key statistical
constraints on their ages, moving group membership, absolute
brightnesses, evolutionary trends, and multiplicity. Targeting isolated
subsets of the population with distinct youth, metallicity, or
atmospheric characteristics for astrometric follow-up creates a well-
calibrated sample which can be used to test how secondary parameters
such as age, metallicity, and dust effect the observable properties of
the population. Since massive, young exoplanets overlap in temperature
with late-type brown dwarfs, such samples are key to understanding
directly-imaged exoplanet data. We propose a continuation of our
approved long-term astrometric program using CTIO 4m + ISPI and CTIO
1.3m + ANDICAM to complete, refine, and/or begin obtaining the parallax
and proper motion for a sample of 20 young brown dwarf/exoplanet-analogs
and 50 low luminosity L/T transition objects ideal for studying how dust
and age effect the population.
