Orbits of HIP 12912. The inserts show a fragment of the speckle autocorrelation image taken in 2024.9 and the zoomed part of the outer orbit with the wobble (full line), SOAR observations (squares), and the center-of-mass trajectory (blue dashed line). Less accurate measurements are plotted by crosses. The magenta ellipse with triangles shows the inner orbit of Ba,Bb.
