Medium‐Resolution Spectra of Normal Stars in the K Band

Abstract

An Atlas of 115 medium-resolution K-band (2.0--2.4 mu m) stellar spectra, spanning spectral types O--M and luminosity types I--V, is presented. K-band spectra are also presented for one N- and one J-type carbon star. A time series of spectra is presented for an S-type Mira variable. All the spectra are at a resolution of ~3000 (1.4 cm-1) and have had the terrestrial absorption removed by dividing by a featureless spectrum. The spectra are plotted with the major spectral features identified and are available digitally.
