Medium-Resolution Stellar Spectra in the L Band from 2400 to 3000 cm-1 (3.3 to 4.2 Microns)
We present a brief atlas of L-band (3.3-4.2 μm) spectra for 42 starsplus the Sun and a sunspot observed at a resolving power of R~3000. Thiscontribution is intended to supplement our previous K-band, H-band, andJ-band spectral atlases. The L-band data, which cover some or all of the2400 to 3000 cm-1 (3.3-4.2 μm) region, are mainly forluminous late-type stars. In reducing these data, special care has beentaken to remove telluric features, especially water vapor. We identifytemperature- and luminosity-sensitive atomic and molecular indices toaid in the classification of stellar spectra in the L band. The data areavailable electronically.
| Low dispersion spectrophotometry of bright early-type stars
Intensity distributions for 79 stars of spectral types O9 to A3, plus anF3 star and 7 standard stars, are presented. The observations cover awavelength range from 3300 to 6000 A. The internal errors are discussed.Synthetic uby colors are obtained for all the stars observed, and arecompared with observed published data.
