A New Library of Stellar Optical Spectra

A new digital optical stellar library is presented. It consists of spectra covering 3510-8930 R at 11 A resolution for 72 different stellar types. These types extend over the spectral classes O-M and luminosity classes I-V. Most spectra are of solar metallicity stars but some metal-rich and metal-poor spectra are included. This new library is quantitatively compared to two previously published libraries. The library has been submitted to the Astronomical Data Center at the NASA Goddard Space Flight Center for convenient distribution
