The infrared overluminosity of young, ultracool substellar objects
Most young, ultracool substellar objects with spectral types later than M9 show very red mid-infrared colors up to 24~micron, significantly redder than expected for their optical and near-infrared spectral classifications. These objects have estimated ages and masses in the intervals 20-300 Myr and 12-35 times the mass of Jupiter, respectively
