BRaVe (Bayesian Radial Velocity Solver) is a Python-based code developed to determines the orbital parameters of double star systems using only time-dependent radial velocity measurements within a Keplerian framework. It uses a Bayesian optimization approach to get reliable orbital solutions with robust uncertainty estimates, and it’s got an integrated CCF module for radial velocity extraction from high-resolution spectra.

The analysis of the time-dependent radial velocity curves of double stars allows direct determination of the physical parameters of the components. The program BRaVe, which we developed to obtain the most accurate orbital modeling, obtains orbital parameters and errors with high precision. BRaVe includes an optimization routine based on Bayesian statistics. This routine aims to obtain the basic orbital parameters of the considered double star system in the most precise way. Capella A was chosen as the reference star for the BRaVe code. Radial velocities were calculated from high-resolution spectra from the Polarbase data archive using the Cross Corelation Function (CCF) method and the orbital parameters were solved using BRaVe. The results obtained in this study are presented and compared with the literature.
