The substellar neighborhood: a stunningly diverse population of brown dwarfs

Abstract: The census of the coldest constituents of the Solar Neighborhood remains incomplete. Completing such census is one of the driving goals for the CatWISE and "Backyard Worlds: Planet Nine" teams, who have discovered hundreds of new late-T and Y dwarfs using data from WISE/NEOWISE. In this poster we present the results of our on-going observing campaign, which is revealing a stunning diversity among the substellar population, a diversity that atmospheric models suggest is driven by metallicity.
