MK classifications of spectroscopic binaries

DOI

New MK spectral classifications are given for 145 spectroscopic binaries (SBs) with A-F primaries because two-dimensional types are lacking for more than one-third of the A-F SBs with known orbital elements in the current catalog. Compared with the classifications by Morgan, Keenan, and their students, the new classifications give types that are 1.1+/-0.2 subclasses later and 0.7+/-0.1 luminosity classes fainter. Also listed are selected published MK types from Brian Skiff's recent compilation (Cat. ).
