RESUMO:
Since the beginning of humanity we have been instigated by questions about our existence and our place in the cosmos, based on questions like this and hypotheses, a new area to be studied by stellar astrophysics, the study of exoplanets gives us before nothing more is the certainty that our planetary system is not unique and that a wide range of Possibilities arise as new discoveries are made in this area of study. This one work aims to provide a historical overview of exoplanetology in addition to publicize the advances made in the area, from the first discoveries to future perspectives, show some basic concepts within this area of study such as the definition of what would be exoplanets and present the most used exoplanet detection methods and responsible for the most recent discoveries. A study was also carried out with 20 curves of light, obtained from the Exoplanet Archive, consisting of 10 stars with planets already confirmed by other studies and 10 stars without confirmed planets. For each of these stars the light curve and probability density graph was created in the R studio program, as well as studied the first four moments of statistical distribution for the flow of this star. In the results we obtained expected patterns for the light curves being eclipsed with periods very close to those found in the literature, and constant flows in the light curves of planetless stars. for statistical moments were also expected patterns were found, considering the limitations of the R studio program and the Kepler telescope.
