Journal ArticleDOI
Spextool: A Spectral Extraction Package for SpeX, a 0.8–5.5 Micron Cross‐Dispersed Spectrograph
TL;DR: In this paper, an IDL-based package called Spextool is described for the reduction of spectral data obtained with SpeX, a medium-resolution, 0.8-5.5 μm cross-dispersed spectrograph and imager for the NASA Infrared Telescope Facility.
Journal ArticleDOI
A Method of Correcting Near‐Infrared Spectra for Telluric Absorption*
TL;DR: In this article, a method for correcting near-infrared medium-resolution spectra for telluric absorption is presented, which makes use of a spectrum of an A0 V star, observed near in time and close in air mass to the target object, and a high-resolution model of Vega.
Journal ArticleDOI
The infrared telescope facility (irtf) spectral library: cool stars
TL;DR: In this article, the authors presented a 0.8-5 μm spectral library of 210 cool stars observed at a resolving power of R ≡ λ/Δλ ~ 2000 with the medium-resolution infrared spectrograph, SpeX, at the 3.0 m NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii.
Journal ArticleDOI
An Infrared Spectroscopic Sequence of M, L, and T Dwarfs*
TL;DR: In this article, a 0.6-4.1?m spectroscopic sequence of M, L, and T dwarfs was presented, which nearly double the number of observed L and T-band spectra.
Journal ArticleDOI

TL;DR: In this paper, Cushing et al. presented ground-based spectroscopic verification of 6 Y dwarfs, 89 T dwarfs and 8 L dwarfs identified by the Wide-Field Infrared Survey Explorer (WISE).
