Medium-resolution spectra of normal stars in the K band

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 similar to 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.
