Em busca de um novo mundo: caracterização de exoplanetas de sistemas planetários de estrelas de Kepler

Abstract

This work aims to study exoplanets observed by the Kepler mission. The research stemsfrom the growing interest in the study and identification of exoplanets, especially those of the terrestrial type. To this end, a comprehensive methodology was developed, covering everything from data acquisition and processing to the detection and characterization of exoplanets, including the creation of a Machine Learning model capable of performing automated exoplanet detection. In addition, the study also delved into aspects related to life, with a focus on extremophile organisms, proposing an algorithm aimed at detecting exoplanets with the potential to harbor this type of life. As a result, 41 exoplanets were detected and characterized, including Kepler-186f, considered to be of high scientific relevance. With the extremophile-oriented algorithm, 161 exoplanets were identified as potentially suitable for sustaining this type of life. Finally, with the developed Ensemble model, it was possible to reproduce the results presented in the article (Armstrong et al., 2021).
