MK classifications of spectroscopic binaries.


Abstract (from CDS):

New MK spectral classifications are given for 145 spectroscopic binaries (SBs) with AF primaries because two-dimensional types are lacking for more than one-third of the AF 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.
