Description

While the study of gravitational waves from merging neutron stars rises as a new tool for physics and astrophysics, observing the electromagnetic neutron stars still provides crucial information necessary to understand their interior composition, and therefore to place constraints on the equation of state of matter at extreme density. A few independent methods permit measurements of the neutron star radius, but the existence of potential systematic uncertainties have been pointed out for these methods. It is therefore necessary to pursue all these in parallel to permit inter-comparison their results. This talk will present an overview these methods to measure the neutron star properties, their recent results, and I will discuss the various observational ways to address the potential systematic uncertainties that may affect the measurements.
