Abstract:
We want to improve the knowledge of orbits, physical parameters and
statistics of nearby multiple systems.
Radial velocities were measured with a correlation spectrometer during
2001-2006 to determine or improve spectroscopic orbits of the
components of some visual multiple systems. We compile all available
observational data and estimate masses and orbital periods in these
hierarchical multiple systems. Masses and ages of evolved components
are derived by fitting isochrones.
Three new spectroscopic orbits of close sub-systems (HD 52452B,
157358Aab, 219877B) are determined and one more orbit (HD 139461) is
improved. The composite-spectrum system HD 157358Aab was resolved by
speckle-interferometry; its preliminary combined orbit is computed to
guide future interferometric observations.
Description:
Individual radial velocities (heliocentric date, velocity, error)
and residuals to orbits are given for components of physical multiple
systems.
