Zona Habitável Circunstelar em torno de estrelas do tipo M

Abstract

This work presents a study of planetary habitability with base in Circumstellar Habitable Zone (CHZ) — which is, for now, the best way to estimate if a planet is minimally habitable without knowing its intrinsic physical conditions —, more specifically around M-type stars, cold and small stars. From this, is preferable to our study the Telluric Circumstellar Habitable Zone (TCHZ) because it’s telluric-mass planets in the CHZ of their stars, i.e, planets more similar to Earth. The main resources used in this work were the models of CHZ and TCHZ developed in the the dissertation written by Fernando de Sousa Mello (São Paulo University, 2014) submitted to M-type stars systems to show what make them (M dwarfs, spectral type M stars on the Main Sequence (MS)) good candidates to host habitable planets. It’s importante to emphasize that this models are a first approximation of the problem, but will be enough for the beginning of this research.
