A Systematic Study Of Nuclear Matter: Finite Nuclei To Neutron Star

TL;DR

This thesis systematically explores nuclear matter properties from finite nuclei to neutron stars using relativistic mean-field models, incorporating recent parameters, exotic nuclei, and dark matter constraints from gravitational-wave observations.

Contribution

It introduces a comprehensive study of nuclear matter across different regimes with updated models and considers dark matter effects within neutron stars, integrating recent observational data.

Findings

Constraints on dark matter variables from gravitational-wave data

Properties of exotic and superheavy nuclei at finite temperature

Implications for neutron star core composition

Abstract

The main aim of the thesis is to study the properties of nuclear matter, i.e., finite nuclei to infinite nuclear matter, at zero and finite temperature within effective field theory motived relativistic mean-field model by using some of the recent parameter sets. For this, we have chosen exotic, superheavy, and natural/neutron-rich thermally fissile nuclei and studied ground as well as excited-state bulk and surface properties of nuclei. We have also tried to figure out the possible constraints on the DM variables by considering WIMP, a DM candidate, inside the NS core and using gravitational-wave data GW170817.
