Dynamical Masses of the Components in o Andromedae
Abstract
It has been shown in earlier papers that o And is a quadruple star. Based on spectroscopic observations, Hill and coworkers calculated the orbital elements for a binary, assigning it to the B component. We have calculated the orbital elements for the subsystems Aa-B and Aa using speckle interferometry measurements. The individual masses of the o And components are determined from the orbital elements for these three subsystems and the trigonometric parallax given in the Hipparcos Catalogue. The results obtained indicate that the A component is a spectroscopic binary.
