The Equation of State of Neutron Stars: Understanding the Densest Objects in the Universe
Presented by Rahul Somasundaram (LANL)
Neutron stars are one of the most fascinating objects in the universe, exploring matter at the highest densities that we can observe. Recent gravitational wave observations of binary neutron star mergers, as well as radio and X-ray observations of millisecond pulsars, have constrained the global properties of neutron stars such as their masses, radii, and tidal deformabilities. This has given us valuable new insights into the Equation of State of dense matter. Simultaneously, there have been significant efforts in the theoretical modeling of the dense matter Equation of State. In this seminar, I will discuss how state-of-the-art nuclear-physics calculations can be used to make predictions for nucleonic matter present in the cores of neutron stars. I will review the impact of such theoretical nuclear-physics inputs and the role they play in interpreting astrophysical data. Additionally, I will explore the plausible existence of exotic, i.e. non-nucleonic matter in neutron stars. I will discuss how one could potentially use the recent experimental data to detect their presence in the inner cores of neutron stars.
