A new research facility is now online hosted by the CWRU Astronomy Department – Prof Earle Luck’s FGK Star Spectral Library.  The library contains high resolution spectra (R from 30000 to 60000 with wavelength coverage from 400 to 700 nm depending on the source) of more than 1500 F,G, and K stars of all luminosity classes including spectra of more than 300 Cepheid variables.  The spectra are available for online inspection, as well as for download.  The number of available spectra is not static – check back periodically for new additions.  This facility is made possible by support from the Mt Cuba Astronomical Foundation.
