A SPHEREx Pipeline and Spectral Library for Ultracool Dwarfs
Jonathan Gagné, Jacqueline K. Faherty, Azul Ruiz Diaz +72
We present a Python spectrophotometry extraction tool tailored for fast-moving point sources detected in the SPHEREx mission, and use it to construct a set of 0.75-5.0 m low-re…
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…
Three Thousand Motion-Confirmed L and T Dwarf Candidates from the Backyard Worlds:~Planet 9 Citizen Science Project
Adam C. Schneider, Marc J. Kuchner, Jacqueline K. Faherty +73
The Backyard Worlds: Planet 9 citizen science project uses data from the Wide-field Infrared Survey Explorer to detect infrared objects with significant motion. In this work, we pr…
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…
