Abstract:
Spectroscopic orbits of the 12 eclipsing binary systems, TW And, CD
And, RS Ari, RU Cnc, TW Cnc, UU Cnc, V788 Cyg, AW Her, MM Her, RV Lib,
EW Ori and ZZ UMa are obtained from Coravel and Elodie radial velocity
measurements. We obtain a first orbit for CD And, RS Ari, TW Cnc, and
V788 Cyg. For the systems TW And, RU Cnc, UU Cnc, AW Her, MM Her, RV
Lib, EW Ori and ZZ UMa, the new spectroscopic orbits are either better
or of quality comparable to that previously published. The physical
properties of these systems were estimated with the photometric
parameters from available data except CD And, TW Cnc, UU Cnc, V788 Cyg
and RV Lib for which we found a model compatible with the
observations. The systems RU Cnc, AW Her, MM Her and RV Lib belong to
RS CVn group. In general these systems were difficult to observe with
Coravel, on the one hand because the stars are relatively weak and on
the other hand because of nature of the components giving peaks of
correlation with weak contrast.
