As taxas para o processo fraco e forte e as respectivas potências irradiadas são calculadas a partir de um formalismo semi-clássico. Nossos resultados são discutidos com respeito aos obtidos na literatura onde se consideram prótons acelerados em campos eletromagnéticos. Testes de consistência são apresentados ao longo desta tese / We investigate the possible decay of protons in geodesic circular motion around neutral compact objects. Weak and strong decay rates and the associated emitted powers are calculated using a semi-classical approach. Our results are discussed with respect to distinct ones in the literature, which consider the decay of accelerated protons in electromagnetic fields. A number of consistency checks are presented along this thesis
