The equation of state and internal composition of neutron stars is not very well constrained yet. In this work, I have used theoretical nuclear physics techniques to predict the bulk properties of neutron stars starting from the Gogny interaction. The results of 10 different parametrizations of this nuclear interaction have been compared to constraints obtained from nuclear physics experiments. Only 1 interaction falls within the available window. I will further compare neutron star properties to astronomical observations and describe how to improve these interactions for dense matter physics.
