A Spitzer Space Telescope Exploration Science Program to Search for Y Dwarf Variability
Michael C. Cushing, Jesica L. Trucks, Kevin K. Hardegree-Ullman +10
We present the results of a Spitzer Space Telescope Exploration Science Program to search for and characterize variability in Y dwarfs. We observed 14 Y dwarfs over a 24 hr period…
Building a Roadmap for Hubble Science into the 2030s: Revealing Atmospheric Structure and Evolution in Substellar Worlds Using HST
Allison M. McCarthy, Merle A. Schrader, Johanna M. Vos +15
Substellar objects occupy a unique place in our universe, bridging the gap between the smallest stars and the largest planets, and serving as powerful laboratories for understandin…
Searching for Ultracool Dwarfs in Early LSST Data Products
Easton J. Honaker, John E. Gizis, Christian Aganze +8
The Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) promises to drastically accelerate the discovery of ultracool dwarfs (UCDs) over the course of its 10-year su…
Simulating Solar Neighborhood Brown Dwarfs I: The Luminosity Function Above and Below the Galactic Plane
Easton J. Honaker, John E. Gizis
Brown dwarfs form the key, yet poorly understood, link between stellar and planetary astrophysics. These objects offer unique tests of Galactic structure, but observational limitat…
JWST 1.5 μm and 4.8 μm Photometry of Y Dwarfs
Loïc Albert, Sandy K. Leggett, Per Calissendorff +20
Brown dwarfs lack nuclear fusion and cool with time; the coldest known have an effective temperature below 500 K, and are known as Y dwarfs. We present a James Webb Space Telescope…
