A library of H band stellar spectra for stellar population analysis purposes
Résumé
A sample of 37 stars of luminosity classes I, III, V, including few SMR stars observed in the H band with a medium resolution (R=1500−2000) is presented. This sample of flux calibrated spectra is intended to widen existing stellar libraries. A new IR spectrograph, ISIS/IR, foreseen for CFHT has been used. Its main characteristics are briefly described. Stellar spectra obtained with this new spectrograph are compared to similar data obtained with the ESO NTT IRSPEC spectrograph. The behaviour of some prominent features is described and it is shown that the CO 1.60/SiI 1.60 line ratio is a good luminosity indicator for stellar types later than K0.
