Spitzer Atlas of Stellar Spectra (SASS) Overview
SASS Overview SASS Primary Data Access IRSA Catalog Search Tool: SASS


The Spitzer Atlas of Stellar Spectra includes 159 stellar spectra (5-32 microns R ~ 100) taken with the Infrared Spectrograph on the Spitzer Space Telescope. This Atlas gathers representative spectra of a broad section of the Hertzsprung-Russell diagram, intended to serve as a general stellar spectral reference in the mid-infrared. It includes stars from all luminosity classes, as well as Wolf-Rayet (WR) objects. Furthermore, it includes some objects of intrinsic interest, such as blue stragglers and certain pulsating variables.
