Position & radial velocity of six triple systems
Listed in IVOA Registry (Virtual Observatory)
Joint analysis of position measurements and radial velocities of six triple stellar systems is conducted to determine their inner and/or outer orbits.
Description
Accumulation of such data is needed to study the architecture of stellar hierarchies and its relation to the formation mechanisms. The inner periods in the six systems (HIP 11783, 64836, 72423, 84720, 89234, and 105404) range from 0.5d to 44yr.
The shortest outer period of 3.34yr is found in the compact triple HIP 105404 (BS Ind). The resolved triple system HIP 64836 has comparable inner and outer periods (5 and 30yr), placing it near the limit of dynamical stability, while its quasi-circular and coplanar orbits suggest a 1:6 mean motion resonance. The periods in HIP 89234 (44 and ~450yr) are also comparable, but the mutual orbit inclination is large, 54{deg}.
