Abstract

Neutron stars (NS) are fascinating objects which hold the key to understanding various aspects of extreme matter physics. Unfortunately, our understanding of the composition of NS decreases as we go from the crust to the core. Therefore, we rely on terrestrial experiments, numerical simulations, and astrophysical observations together to constrain the equation of state (EoS) inside the NS. The key is to map this EoS to the observables like NS mass and radius. This map, for non-rotating cold NS, is facilitated by the Tolman-Oppenheimer-Volkoff (TOV) equation. In this talk, I will give a glimpse of how information from different extreme matter probes is glued together to make sense of the current and future observations of NS. With this understanding, I am going to explain our work where we have developed a neural network-based TOV solver to map the EoS to NS mass and radius.
