Mid-infrared followup of cold brown dwarfs: Diversity in age, mass and metallicity
We use Spitzer IRAC 3.6–8.0 μm photometry of late-type T dwarfs to investigate various trends which can aid the planning and interpretation of infrared (IR) surveys for the coldest T or Y dwarfs. Brown dwarfs with effective temperature (Teff)<700 K emit>50% of their flux at λ>3 μm, and the...
