Summary: The neutron star is a compact structure in which gravitational forces are supported by neutron degenerescence. This structure born with the end of nuclear fusion, following a exploding process, called supernova. In addition, its constituent materials are in extreme conditions, the density in these structures are of order of nuclear saturation, in this context the used of general relativity is essential. In general, the Einstein's theory together with the equation of state is used to to this end. But the fact of not knowing with precision the behavior of the matter and the physics, in a certain way, in this extreme regime,
makes room to use the alternatives theories to describe these stars. In this context, in this thesis we will study consequences, in the neutron stars structure, when we use the some alternatives model the Newtons's and Einstein's theories. Thus we will show an alternative for the rst approximated non relativistic for this structure, we will propose
a possible limitation for Rastall's parameter - and the vacuum solution for this theory - and we will do an analise the relevance of the terms to relativistic corrections.
