Abstract:
Spectroscopic orbits are determined for inner subsystems in nine stellar
hierarchies (HIP 2863, 4974, 8353, 28796, 35261, 92929, 115272, 115552,
and 117596). Their periods range from 2.5 to 312 days. For each system,
estimates of masses, orbital inclination, and other parameters are given.
Description:
The spectra used here were taken with the 1.5 m telescope sited at the
Cerro Tololo Inter-American Observatory (CTIO) in Chile and operated
by the SMARTS Consortium (http://www.astro.yale.edu/smarts). The observing
time was allocated through the National Optical Astronomy Observatory
(NOAO). Observations were made with the CHIRON optical echelle spectrograph
(Tokovinin et al. 2013PASP..125.1336T 2013PASP..125.1336T) by the telescope operators in
service mode. The RVs are determined from the cross-correlation function
(CCF) of echelle orders with the binary mask based on the solar spectrum,
as detailed in Tokovinin (2016, J/AJ/152/11).

Note (1): For single-lined systems, the mass of the primary star is estimated
from its absolute V magnitudes, and the minimum mass of the secondary that
corresponds to the 90° inclination is derived from the orbit.
