Abstract.A large sample of visual multiples of spectral types F5-M has been surveyed for the presence of spectroscopic sub-systems. Some 4200 radial velocities of 574 components were measured in 1994-2000 with the correlation radial velocity meter. A total of 46 new spectroscopic orbits were computed for this sample. Physical relations are established for most of the visual systems and several optical components are identified as well. The period distribution of sub-systems has a maximum at periods from 2 to 7 days, likely explained by a combination of tidal dissipation with triple-star dynamics. The fraction of spectroscopic sub-systems among the dwarf components of close visual binaries with known orbits is similar to that of field dwarfs, from 11% to 18% per component. Sub-systems are more frequent among the components of wide visual binaries and among wide tertiary components to the known visual or spectroscopic binaries -20% and 30%, respectively. In triple systems with both outer (visual) and inner (spectroscopic) orbits known, we find an anti-correlation between the periods of inner sub-systems and the eccentricities of outer orbits which must be related to dynamical stability constraints.

“…This because our aim is to evidentiate the possibility that the presence of a companion might jeopardize the measurements. The informations we give generally concern the ADS number (Aitken 1932), if available, the angular distance in arcsec, and the magnitude difference between the components. The spectroscopic binary character is indicated if the period is known; these data are mainly from Batten et al (1978) catalogue.…”

Abstract. A catalogue of all the periods up to now proposed for the variations of CP2, CP3, and CP4 stars is presented. The main identifiers (HD and HR), the proper name, the variable-star name, and the spectral type and peculiarity are given for each star as far as the coordinates at 2000.0 and the visual magnitude. The nature of the observed variations (light, spectrum, magnetic field, etc.) is presented in a codified way.

“…Some observations were also made by the author in 1994 with the CORAVEL spectrometer (Baranne et al 1979) at the Haute Provence Observatory. Table 1 contains the identification data on the 7 systems: IDS (1900) index, ADS number (Aitken 1932), HD or BD number, equatorial coordinates for 2000.0 and other identifiers, e.g. double star discoverer codes.…”

Abstract. New close sub-systems are discovered in wide physical multiple stars. Elements of spectroscopic orbits are given for the components of quadruple systems ADS 1315C, 3608C, 3824C, 3991A and for the components of triple systems ADS 1849A, 6646A, 8861A. Physical parameters (magnitudes, spectral types, masses of individual components, distances to the systems, angular separations) are estimated by combining all available data. The nearby M dwarf ADS 8861A = Gliese 507A is a good candidate for speckle resolution. The very hot white dwarf discovered by Hodgkin et al. (1993) is likely to be an additional visual component to ADS 3824C, so this system may be quintuple; however, a search of 2.d 993 photometric periodicity possibly caused by the hot close companion is highly desirable.
