Description :
Double-lined spectroscopic binaries (SB2s) are one of the main sources of stellar masses, as additional observations are only needed to give the inclinations of the orbital planes in order to obtain the individual masses of the components. For this reason, we are observing a selection of SB2s using the SOPHIE spectrograph at the Haute-Provence observatory in order to precisely determine their orbital elements. Our objective is to finally obtain masses with an accuracy of the order of one percent by combining our radial velocity (RV) measurements and the astrometric measurements that will come from the Gaia satellite. We present here the RVs and the re-determined orbits of 10 SB2s. In order to verify the masses we will derive from Gaia, we obtained interferometric measurements of the ESO VLTI for one of these SB2s. Adding the interferometric or speckle measurements already published by us or by others for 4 other stars, we finally obtain the masses of the components of 5 binary stars, with masses ranging from 0.51 to 2.2 solar masses, including main-sequence dwarfs and some more evolved stars whose location in the HR diagram has been estimated.

Data acquisition methods :
  • Derived or compiled data :
    The RVs of the components are derived using the TwO-Dimensional CORrelation algorithm todcor (Zucker & Mazeh 1994ApJ...420..806Z; Zucker et al. 2004, Cat. J/A+A/426/695).
  • Observational data :
    10 spectroscopic binary stars (SB2s) were observed using the SOPHIE spectrograph at the Haute-Provence observatory (France) in order to precisely determine their orbital elements. These observations were complemented by interferometric measurements of the ESO VLTI for one of these SB2s and by interferometric or speckle measurements already published by us or by others for 4 other stars.
