Spectroscopic orbits for K giants β Reticuli and ν Octantis: What is causing a low-amplitude radial velocity resonant perturbation in ν Oct?
New astrometric-spectroscopic orbital solutions for the single-line K-giant binaries β Reticuli (P ≈ 5.2 yr, e = 0.3346 ± 0.0004) and ν Octantis (P ≈ 2.9 yr, e = 0.2358 ± 0.0003) have been derived based on high-precision spectroscopic radial velocities (RVs) and the Hipparcos astrometry. For the cas...
