Exoplanetaryastronomy is a fast growing area of modern astronomy which objects of research are extrasolar planets and systems they form. Among the problems solved within this area, searching of new exoplanetary systems will shed light on processes of the birth and evolution of planets of our Solar system including the Earth. In this article we present results of first follow-up observationsof transitingexoplanet candidatesdiscovered using «MASTER-II» telescope. Follow-up observations allowed us to estimate periods more precisely, however further photometric and spectroscopic researches are necessary for clarification of true objects nature
