Infrared spectroscopy of substellar objects in Orion
We present broad-band spectra of a sample of 21 low-luminosity sources in the Trapezium cluster, with masses in the range 0.008–0.10 M⊙ (assuming an age of 1 Myr). These were selected for low extinction in most cases, and are located west of the brighter nebulosity. The spectra are in the …
