Abstract (from CDS):

We present the results of a radial velocity (RV) study of five new SB1 spectroscopic binaries with composite spectra: HD 3210/1, 27395, 39847, 70826 and 218257/8. We analyse the composition of those objects which are found to be triple systems (at least): all of them include a cool evolved star, a hot star of type B or A and a third component.

From the RV measurements of the cool components, we derive the orbital elements of the corresponding spectroscopic binaries for the first time. Their analysis leads us to propose a model which describes the nature of the individual components of those five systems, with some predictions on their angular separations and magnitudes. In some cases, the spectroscopic companion of the cool component is not the hot star contributing to the composite spectrum.
