Abstract:
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. B/mk).
Description:
The photographic spectra were obtained with the Meinel Cassegrain
spectrograph on the Kitt Peak 0.9m telescope.

Note (1): Eighth catalog of the orbital elements of spectroscopic binary
(SB8) systems by Batten et al. (Cat. V/64, <SBC8 NNNN> in Simbad) is
obsoleted by the ninth catalog (SB9) (Pourbaix et al., Cat. B/sb9;
<SBC9 NNNN> in Simbad).
Note (2): Other designations as from:
HR = Hoffleit and Jaschek, Cat. V/50,
in Simbad
ADS = Aitken, 1932ADS...C......0A 1932ADS...C......0A ; in Simbad
IDS = Jeffers et al., 1963IDS...C......0J 1963IDS...C......0J ; in Simbad
Note (3): Tells whether the star is a single-lined (SB1) or double-lined
(SB2) system. For SB2s there may be two types given in the following
columns if their spectra show obvious composite spectra; otherwise the
types are blends of the two.
Note (4): Obtained mostly from the many published choices offered by B.
Skiff, Cat. B/mk. In selecting one for each star, we gave preference
to classifications by Morgan and Keenan, their students (Abt,
Bidelman, Cowley, Garrison, Roman, and Slettebak), and their
students' student (Gray).
