Orbital Elements and Individual Component Masses from Joint Spectroscopic and Astrometric Data of Double-line Spectroscopic Binaries*

We present orbital elements, parallaxes and individual component masses, for fourteen spatially resolved double-line spectroscopic binaries derived doing a simultaneous fit of their visual orbit radial velocity curve. This was done by means Markov Chain Monte Carlo code developed our group, which produces posterior distribution functions error estimates all the parameters. Of this sample, six systems had high quality previous studies were included as benchmarks to test procedures, but even in these cases we could improve orbits adding recent data from survey southern being carried out with HRCam ZORRO speckle cameras at SOAR 4.1m Gemini South 8.1m telescopes, respectively. also give results eight objects that did not have published combined solution, one either. determine mass ratios typical uncertainty less than 1%, sums uncertainties about 1% masses formal $0.01 M_\odot$ best cases. A comparison available trigonometric Hipparcos Gaia eDR3, shows good correspondence; mean value differences consistent zero within errors both catalogs. observational HR diagrams sample binaries, combination isochrones different sources allowed us asses evolutionary status photometry.
