Spectro. of Subsystems in Multiple Stars. VIII.

DOI

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).
