Abstract
We describe an ongoing project to obtain a library of high signal-to-noise, high spectral resolution stellar spectra from ~1-5 micrometer using CRIRES on the ESO Very Large Telescope (VLT). New instrumental capabilities make the near-infrared an increasingly important wavelength range for high resolution spectroscopy, yet our knowledge of the spectral features in these regions is far from complete. The motivations of our group in conducting this survey are broad, from providing fundamental line data for laboratory spectroscopists, improving wavelength calibration and the removal of telluric lines for CRIRES to applications in astrophysical topics from observations of circumstellar matter to modelling stellar atmospheres. Substantial effort is being invested in producing a library of spectra reduced using a common procedure to ensure homogeneity of the results. So far, we have obtained spectra of 9 sources and hope to complete a sample size of ~25 to give good coverage of the HR diagram. Most of our targets were selected from the UVES-POP spectral library source list, so that complete coverage of the spectra from the UV to the NIR will be available. An important goal for the project is that the library is public.
