- W2435173311 abstract "The bulk properties of spherically symmetric stars in general relativity can be obtained by integrating the Tolman-Oppenheimer-Volkoff (TOV) equations. In previous work we developed a post-TOV formalism - inspired by parametrized post-Newtonian theory - which allows us to classify in a parametrized, phenomenological form all possible perturbative deviations from the structure of compact stars in general relativity that may be induced by modified gravity at second post-Newtonian order. In this paper we extend the formalism to deal with the stellar exterior, and we compute several potential astrophysical observables within the post-TOV formalism: the surface redshift $z_s$, the apparent radius $R_{rm app}$, the Eddington luminosity at infinity $L_{rm E}^infty$ and the orbital frequencies. We show that, at leading order, all of these quantities depend on just two post-TOV parameters $mu_1$ and $chi$, and we discuss the possibility to measure (or set upper bounds on) these parameters." @default.
