Thermal evolution of neo-neutron stars. II. Temperature-dependent crusts

Sagnik Chatterjee, Mikhail V. Beznogov, Dany Page +1

The neo-neutron star phase is an intermediate stage in the evolution from a hot lepton-rich compact object, which is formed in the aftermath of a core-collapse supernova or an accr…

Distinct Signatures of the Nature of Phase Transition in Binary Neutron Star Mergers

Sagnik Chatterjee, Shamim Haque, Kamal Krishna Nath +2

Binary neutron-star mergers offer crucial insights into the matter properties of neutron stars. We present the possible imprints in the gravitational wave signal from the nature of…

Insights Into Neutron Stars From Gravitational Redshifts and Universal Relations

Sagnik Chatterjee, Kamal Krishna Nath

The universal relations in neutron stars form an essential entity to understand their properties. The moment of inertia, dimensionless tidal deformability, mass quadrupole moment,…

Prospect of unraveling the first-order phase transition in neutron stars with and modes

Pratik Thakur, Sagnik Chatterjee, Kamal Krishna Nath +1

Quasi-normal modes of neutron stars are an exciting prospect for analyzing the internal composition of NSs and studying matter at high densities. In this work, we focus on studying…
