Radial velocity in multiple systems
Listed in IVOA Registry (Virtual Observatory)
We want to improve the knowledge of orbits, physical parameters and statistics of nearby multiple systems.
Description
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.
