RVs & positions of 4 hierarchical systems
Listed in IVOA Registry (Virtual Observatory)
Adding to the large radial velocity survey of nearby solar-type stars (summary in Tokovinin, 2023a), spectroscopic orbits are determined for four hierarchical systems: HIP 49442 (inner and outer periods of 164.55days and 34yr, respectively), HIP 55691 (2.4 and 415yr), HIP 61465 (86.8days), and HIP 78662C (0.82day).
Description
Each system is discussed individually. Seven Gaia orbits of low-mass dwarfs, each with two additional resolved (interferometric and wide) companions, i.e., potential quadruples, are tested by monitoring radial velocities: five orbits are confirmed and two are refuted.
Five of these systems are quadruples of 3+1 hierarchy, one is quintuple, and one is triple. Strengths and limitations of the Gaia data on multiple systems and the need of complementary observations are highlighted.
