Subsystems orbits in multiple stars. IX
Listed in IVOA Registry (Virtual Observatory)
New spectroscopic orbits of inner subsystems in 14 hierarchies are determined from long-term monitoring with the optical echelle spectrometer, CHIRON.
Description
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.
