NICS-TNG Low-Resolution 0.85–2.45 micron Spectra of L Dwarfs: A Near-Infrared Spectral Classification Scheme for Faint Dwarfs

NICS-TNG Low-Resolution 0.85–2.45 micron Spectra of L Dwarfs: A Near-Infrared Spectral Classification Scheme for Faint Dwarfs

We present complete near-infrared (0.85-2.45 μm), low-resolution (~100) spectra of a sample of 26 disk L dwarfs with reliable optical spectral type classification. The observations have been obtained with the Near Infrared Camera and Spectrograph at the Telescopio Nazionale Galileo using a prism-based optical element (the Amici device) that provides …
