MAST Spectral Classes of Like Stars

Metadata Updated: September 19, 2025

This table was created by cross correlating entries from the MAST "Table of Representative Spectra" with targets listed in the Skiff Spectral catalog, the Sky2000 catalog, and/or provided by Simbad. Spectra from IUE, STIS, FUSE, EUVE, HUT, GHRS, FOS, WUPPE, BEFS, and TUES are included. Most correlations were based on cross-matching target names and coordinates, usually with a 5" tolerance, but a few matches may be wrong. The table lists roughly 28,000 observations including novae and supernovae of which more than 22,000 have assigned spectral types.
