Abstract:
Periods, eccentricities, and masses in hierarchical stellar systems
inform us on the formation and early evolution of these fascinating
objects. To complement the multiplicity statistics of nearby
solar-type stars, 19 new spectroscopic orbits of inner subsystems in
15 hierarchies (10 triples and 5 quadruples) are determined based on
high-resolution echelle spectra collected during several years. While
previous papers of this series contained mostly short-period orbits,
here most periods are on the order of a year. The main components of
these hierarchies are HIP7852, HIP9148, HIP12548, HIP21079, HIP24320,
HIP27970, HIP34212, HIP56282, HIP57860, HIP76400, HIP76816, HIP81394,
HIP96284, HIP100420, and HD108938. Noteworthy systems are HIP12548 and
HIP24230 (hierarchies of 2+2 architecture with low-mass spectroscopic
secondaries), HIP 56282 (a planetary-type 3+1 hierarchy), and HIP
27970 (a compact triple with periods of 15 and 1049 days).
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. Fifteen hours of observing time were allocated to this
program per semester. Observations were made with the fiber-fed CHIRON
optical echelle spectrograph (R∼85000).
