A Near-infrared Spectral Library of Very Young Brown Dwarfs and Planetary Mass Objects in the Orion Nebula Cluster

The Astrophysical Journal
Age-benchmark brown dwarf and planetary-mass-object spectroscopy is key to characterizing substellar evolution. In this paper, we present the JHK medium-resolution ( R ∼ 3000) spectra of 25 7–76 M _Jup (spectral types L3.0–M6.0) brown dwarfs and ...
