Abstract

This dissertation, written as a compendium of research articles, was proposed and supervised by J.A. Docobo, Full Professor in Astronomy and Director of the Ramon María Aller Astronomical Observatory of the University of Santiago de Compostela. The focus is on the practical application of speckle interferometry techniques, including the initiation and development of several observational campaigns employing OARMA's eMCCD speckle camera attached to the 2.6m telescope at BAO. Additionally, we present 26 orbits of accessible binaries of the Southern hemisphere based on SOAR speckle data. Also, the orbital information of the double-line spectroscopic binaries, HD 183255, HD 114882, and HD 30712, together with new speckle measurements performed using large telescopes, allowed us to determine the main physical parameters of these systems.
