Título: Identification of stellar companions to exoplanets host stars

Resumo: We intend to apply the speckle interferometry technique, recently developed at OPD, to identify the possible presence of companions associate to a sample of confirmed (or candidates) southern exoplanet host stars. The confirmation (or not) of binarity is extremely important for a better interpretation of exoplanet signals and the correct characterization of the planetary systems. This information is also critical for the comprehension of possible planetary formation scenarios, the orbital stability of planetary systems and also for the determination of habitable zones in binary systems.
