Equivalent widths of absorption lines in the spectra of 20 stars of luminosity class III.
Abstract
A catalog of equivalent absorption-line widths is presented for 20 nonvariable stars of luminosity class III and spectral types ranging from B9 to G0. The equivalent widths were determined from a total of 92 spectrograms of the 20 stars, which include only one peculiar star and no binaries. Equivalent widths and rms errors are listed for all absorption lines in the range from 3721.9 to 4861.3 A in each stellar spectrum. It is noted that the ultimate goal of the present work is the two-dimensional quantitative classification of RR Lyrae variable stars on the basis of an analogous classification of nonvariable stars of the same spectral types.
