Abstract:
Results of a large program of spectroscopic monitoring of nearby
solar-type stellar hierarchical systems using the CHIRON echelle
spectrograph at the 1.5m telescope are summarized. Ten papers of this
series contain 102 spectroscopic orbits and substantially contribute
to the knowledge of periods and eccentricties, providing input for the
study of their formation and early evolution. Radial velocities of an
additional 91 targets without CHIRON orbits (members of wide physical
pairs) are published here. Our results are compared to the recent Gaia
nonsingle star (NSS) catalog, revealing its strengths and weaknesses.
The NSS provides orbital periods for 31 objects of the CHIRON sample
(about one third). Of the 22 spectroscopic NSS orbits in common, 14
are in good agreement with CHIRON, the rest have reduced velocity
amplitudes or other problems. Hence ground-based monitoring gives, so
far, a more accurate and complete picture of nearby hierarchies than
Gaia. The distribution of inner periods in hierarchical systems is
nonmonotonic, showing a shallow minimum in the 30-100 days bin and a
strong excess at shorter periods, compared to the smooth distribution
of simple binaries in the field. The period-eccentricity diagram of
inner subsystems updated by this survey, recent literature, and Gaia,
displays an interesting structure.
