Infrared spectroscopy of substellar objects in Orion

Abstract:

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 H bandpass (1.4-1.95 μm) and K bandpass (1.9-2.5 μm) also for most of the brighter sources, with a resolution of 50 nm. They were taken with the United Kingdom Infrared Telescope (UKIRT) using the CGS4 spectr...
