Abstract:
New close sub-systems are reported and studied in eight visual
multiple systems. Elements of one double-lined and eight single-lined
spectroscopic orbits are given. Magnitudes, colors, spectral types,
masses of individual components are estimated by combining all
available data. The visual secondary component of the young binary
HD 27638 is a double-lined pair of G-type dwarfs on a 17-day orbit
with an unseen but massive (>1.2M☉) spectroscopic tertiary on an
8-year orbit. The invisible secondary of HD 28271A is also massive,
but it is not seen probably owing to a high luminosity of the primary
- an F7 star with fast axial rotation and active chromosphere which
evolves off the Main Sequence. Two additional companions are found in
the visual triple system HD 179484.
