Universidad de Sevilla, Sevilla.https://hdl.handle.net/11441/164267Gravitational waves are ripples in the fabric of spacetime, predicted by Einstein while developing the theory of General Relativity. This prediction got indirectly proven firstly by Hulse and Taylor in 1981, which won the Nobel prize for them in 1993 and afterwards directly proven by the association Ligo in 2015, observation which lead to another Nobel prize in 2017. In this work I have carried out the full analytical derivation of the energy loss a source undergoes due to the emission of gravitational waves, which can be detected as a decrease of the orbital period of a binary system. To measure this predicted decrease of orbital period, Russel Hulse and Joseph Taylor measured the signal emitted by the binary pulsar PSR B1913+16 obtaining measurements which agreed with the expected. So, after the derivation of the equation which describes the energy loss, I have revised the methods and considerations used to make this observation. Additionally, I have carried a numerical analysis on how the emission of energy depends on the properties of the binary system. This way, I have studied at what points of the parameter space of a binary system the expected loss of orbital period is detectable. In general, this work not only serves as an example of an observational technique to prove General Relativity predictions but it also shows how the effects which arise from General Relativity has proven useful for the study of the properties of binary pulsars in Astrophysics.application/pdf60 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
