Inner & outer orbits in 13 multiple stars systems
Listed in IVOA Registry (Virtual Observatory)
Orbits of inner and outer subsystems in 13 triple or higher-order stellar systems are computed or updated using position measurements and, in three cases, radial velocities.
Description
The goal is to determine mutual orbital inclinations, period ratios, and masses to complement the statistics of hierarchical systems. The effect of the subsystems on the motion in the outer orbits (wobble) is explicitly modeled to determine inner mass ratios.
Stars studied here (HD 5408, 8036, 9770, 15089, 29310, 286955, 29316, 140538, 144362, 154621, 156034, 185655, and 213235) are bright and nearby (from 15pc to 150pc). Their inner periods range from 1.7yr to 49yr, and the outer periods from 83 to 2400yr. Some long-period outer orbits are poorly constrained.

Four astrometric inner orbits and one outer orbit are computed for the first time.
