Thousands of exoplanets have been discovered in just a few decades. The number of known planets increases at an ever faster pace as well as the missions dedicated to detect more planets. The diversity that we find challenges us to study them in depth and to know in detail their physical properties, how they have been formed and which are the mechanisms that govern their evolution. Motivated by the recent advances in this area, we identified a group of hot jupiters that fulfill the necessary conditions to characterize in the future their atmospheres. In a previous work we published a photometric analysis of the selected sample of exoplanets based on data obtained with Argentine telescopes and recently released by the TESS mission. In this work, we focus on the radial velocity data existing in the literature and we re- analyze them using a code of our own to compare our results with the published ones and advance to the simultaneous study of all the existing information.
