Description:
Individual radial velocities (heliocentric date, velocity, error) and
residuals to orbits are given for components of 7 wide physical
multiple systems.
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 2.993d photometric periodicity
possibly caused by the hot close companion is highly desirable.
