Newtonian I-Love-Q relations: An enthalpy-based approach
Athul Kunjipurayil, J. Piekarewicz
We present a pedagogical introduction to the I-Love-Q relations within Newtonian gravity using an enthalpy-based formulation of stellar structure. Introducing the specific enthalpy…
Thermodynamic versus Dynamical Description of the Neutron-Star Crust-Core Instability: Implications for Crustal Observables
Athul Kunjipurayil, J. Piekarewicz
We investigate the crust-core transition in neutron stars using both thermodynamic and dynamical descriptions of the instability. In the thermodynamic approach, the transition is i…
Elucidating the role of the surface energy in density functional theory
Md Jafrul Islam, Athul Kunjipurayil, J. Piekarewicz +1
The saturation of symmetric nuclear matter -- reflected in the nearly constant interior density of heavy nuclei -- is a defining property of nuclear matter. Modern relativistic ene…
Role of the isovector spin-orbit potential in mitigating the CREX-PREX dilemma
Athul Kunjipurayil, Marc Salinas, J. Piekarewicz
Pioneering electroweak measurements of the neutron skin thickness in lead-208 and calcium-48 are challenging our understanding of nuclear dynamics. Many theoretical models suggest…
Impact of the equation of state on - and - mode oscillations of neutron stars
Athul Kunjipurayil, Tianqi Zhao, Bharat Kumar +2
We investigate the impact of the neutron-star matter equation of state on the - and -mode oscillations of neutron stars obtained within the Cowling approximation and linear…
Radial oscillations in neutron stars from unified hadronic and quarkyonic equation of states
Souhardya Sen, Shubham Kumar, Athul Kunjipurayi +3
We study radial oscillations in non-rotating neutron stars by considering the unified equation of states (EoSs), which support the 2 M star criterion. We solve the Sturm-Li…
