2-14 μm stellar spectrophotometry. I. Stars of the conventional spectral sequence.

Abstract

Infrared spectrophotometry with resolution A/A 0.015 over the wavelength range 2-14 m is presented for a wide variety of stars of the conventional spectral sequence. The progression of the strength of discrete spectral features due to gaseous molecules in the stellar atmospheres as well as those features attributable to circumstellar grains is illustrated and discussed. Key words: late-type stars - carbon stars - molecular spectra - infrared spectrophotometry
