J/A+A/382/118     Spectroscopic sub-systems in multiple stars (Tokovinin+, 2002)

Statistics of spectroscopic sub-systems in visual multiple stars Tokovinin A.A., Smekhov M.G. <Astron. Astrophys. 382, 118 (2002)> =2002A&A...382..118T
ADC_Keywords: Stars, double and multiple ; Binaries, spectroscopic ; Radial velocities ; Rotational velocities Keywords: binaries: visual - binaries: spectroscopic Description: A large sample of visual multiples of spectral types F5-M has been surveyed for the presence of spectroscopic sub-systems. In table 1 we provide basic identifiers for the components or their combinations, average radial velocities, parameters of correlation dips and analysis of the velocity variability and physical relation. Notes contain comments and additional identifiers. Individual radial velocities yet unpublished are listed in table 2. Table 6 is extracted from the Multiple Star Catalog (Cat. J/A+AS/124/75) for the analysis of the statistics of spectroscopic+visual multiple stellar systems. File Summary:

Note (1): If more than two unresolved visual components, '+' appears. Note (2): If upper limits on Vsin(i) are given here instead of errors, this is indicated by '*' in column 82. Note (3): Variability status: C: constant C?: likely constant V: variable V?: likely variable VO: variability likely due to visual orbital motion S1O: single-lined binary with orbit S2O: double-lined binary with orbit Asterisk indicates possible mixture of partially resolved components affecting the velocity precision and equivalent width. Note (4): Physical relation to other components: *: primary component or components of a multiple system P: physical component P?: likely physical component O: optical component O?: likely optical component Note (5): Flag for three statistical sub-samples: B: visual binaries with known orbits D: wide resolved visual binaries T: tertiary components to physical binaries
