Abstract:
New close sub-systems are discovered in 8 visual late-type double
stars. Elements of spectroscopic orbits (4 double-lined and 4
single-lined) are given for the components of quadruple systems
ADS 1134 and 11163, for the components of triple systems ADS 455, 497,
5436, 8236, 10044, and for the primary of the optical pair ADS 9444.
Magnitudes, colors, spectral types, masses of individual components
are estimated by combining all available data with Hipparcos
parallaxes. Among these stellar systems we note a subdwarf triple ADS
497, an old system with subgiant components ADS 10044, and a visual
triple ADS 11163 with additional very low mass (possibly substellar)
spectroscopic companion in a 4.6 day orbit. The astrometric orbit of
ADS 8236B with a semimajor axis of 30 mas and a period of 4.6 yr may
be recoverable from Hipparcos data.
