Title: Realistic simulations of relativistic plasmas, astrophysical implications and multimessenger constraints on the nuclear equation of state
Abstract:
In this seminar, I will give an overview of results produced by the Astroparticle and Nuclear Astrophysics Group at the University of Salamanca, within the context of my PhD thesis. In the first part, I will describe our Molecular Dynamics (MD) code capable of realistically simulating relativistic, fully-ionized plasmas in neutron stars and white dwarfs interiors. I will explain how transport and elastic properties are relevant for gravitational wave physics, and the importance of realistically characterizing the electrostatic sector of the crust Equation of State (EoS) at finite temperature. Secondly, I will discuss our contributions to constrain the Nuclear Equation of State from multimessenger signals from kilonovae. Ejected matter radioactively powers the electromagnetic emission, which contains critical information about size, compactness and tidal deformability of the binary stars. This is crucial for connecting the microscopic properties of the EoS with the observables from future binary neutron star merger multimessenger observations.
