#### Parallel session 9 (Neutron Stars)

- Session convener: Violetta Sagun

The behaviour of extremely dense cold nuclear matter is still an open question due to intrinsic modelling difficulties of such extreme environments as the hearts of Neutron Stars (NS), but also to the non-trivial connection between the macroscopic observables and microscopic behaviour. In this work, we utilize the now substantial amount of astrophysical data provided by NS observations, along...

The $I$-Love-$Q$ relations refer to the existence of various approximate equation of state-independent relations involving the moment of inertia, Love number, and quadrupole moment. These relations have an interesting applicability in observational astrophysics since they allow the inference of two quantities within the $I$-Love-$Q$ trio out of a third one alone. However, the quantities...

Relativistic stars are typically modelled as ideal fluids, which in spherical symmetry leads to the Tolman-Oppenheimer-Volkoff (TOV) solutions. In this talk I discuss the construction of solutions for spherical, relativistic stars within full kinetic theory. In this case matter is described by the Vlasov-Boltzmann equation, which allows for a more realistic description of stars that is valid...
