Abstract:
In this paper, we will analyze a theory of modified gravity, in which the field content of general relativity will be increased to include a vector field. We will use
the Horndeski formalism to non-minimally couple this vector field to the metric. As we will be using the Horndeski
formalism, this theory will not contain Ostrogradsky ghost
degree of freedom. We will analyze compact stars using this
vector–tensor-Horndeski theory
