Abstract:
New spectroscopic orbits of inner subsystems in 14 hierarchies are
determined from long-term monitoring with the optical echelle
spectrometer, CHIRON. Their main components are nearby solar-type
stars belonging to nine triple systems (HIP3645, 14307, 36165, 79980,
103735, 103814, 104440, 105879, 109443) and five quadruples of 2+2
hierarchy (HIP41171, 49336, 75663, 78163, and 117666). The inner
periods range from 254days to 18yr. Inner subsystems in HIP3645,
14313, 79979, 103735, 104440, and 105879 are resolved by speckle
interferometry, and their combined spectro-interferometric orbits are
derived here. Astrometric orbits of HIP49336Aa,Ab and HIP117666Aa,Ab
are determined from wobble in the observed motion of the outer pairs.
Comparison with three spectroscopic orbits found in the Gaia data
release 3 archive reveals that Gaia underestimated the amplitudes
(except for HIP109443), while the periods match approximately. This
work contributes new data on the architecture of nearby hierarchical
systems, complementing their statistics.
Description:
The spectra used here were taken with the 1.5m telescope sited at the
Cerro Tololo Inter-American Observatory (CTIO) in Chile and operated
by the Small and Medium Aperture Telescopes Research System (SMARTS)
Consortium. Observations were made with the fiber-fed CHIRON optical
echelle spectrograph by the telescope operators in service mode. The
spectra taken with the image slicer have a resolution of 85000.
