I-Love-Q

Abstract

Neutron stars and quark stars are not only characterized by their mass and radius, but also by how fast they spin, through their moment of inertia, and how much they can be deformed, through their Love number and quadrupole moment. These depend sensitively on the star's internal structure, and thus on unknown nuclear physics. We find universal relations between the moment of inertia, the Love number and the quadrupole moment that are independent of the neutron star's and quark star's internal structure. These can be used to learn about the deformability of these compact objects through observations of the moment of inertia, break degeneracies in gravitational wave detection to measure spin in binary inspirals and test General Relativity in a nuclear-structure independent fashion.

6 pages, 3 figures; Quark-star Love number calculations corrected. The quark-star I-Love-Q relations now lie on top of the neutron-star ones
