Dissertação (Mestrado em Física) - Universidade Federal de Alfenas, Poços de Caldas, 2019.http://repositorioteste.unifal-mg.edu.br/handle/123456789/1505This dissertation begins with a bibliographic study about the invariance of Maxwell electrodynamics towards Lorentz transformations. After it is discussed about the metric of a not charged and static black hole, as first proposed by Schwarzschild. Following this, it is presented the solution to a charged and static black hole, as calculated by Reissner-Nordström. Then the attention is turned to the thermodynamic description of a static and charged black hole, governed by the no linear electrodynamics of Euler-Heisenberg theory, using the analogy with statistical thermodynamics as suggested by Jacob Bekenstein and Stephen Hawking. In the end, it is calculated the horizons' radios for different systems according to the ration of charge/mass and then it is analysed the light cones in states where the horizons have nearly the same value.application/pdfAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Eletrodinâmica.Cosmologia.Buracos negros (Astronomia).Campos gravitacionais.Teoria de campos (Física).CIENCIAS EXATAS E DA TERRA::ASTRONOMIADissertaçãoMelo, Cássius Anderson Miquele De
