Summary of universal relations in various gravity theories

Overview of neutron star models in alternative theories

Identification of gaps for future research

Abstract

This is a review with the ambitious goal of covering the recent progress in: 1) universal relations (in general relativity and alternative theories of gravity), and 2) neutron star models in alternative theories. We also aim to be complementary to recent reviews in the literature that are covering the topic of universal relations of neutron stars.
