Universality in spacetime modes of quarkyonic stars

D. Dey, Jeet Amrit Pattnaik, R. N. Panda +1

The gravitational wave mode spectrum presents a unique window into the dense interior of neutron stars, probing physics inaccessible to electromagnetic observations. This work…

Anomalous Behavior of Giant Monopole Resonance Energy with Nuclear Matter Incompressibility in the framework of Relativistic Mean Field Formalism and Coherent Density Fluctuation Model

Jeet Amrit Pattnaik, R. N. Panda, M. Bhuyan +1

The finite nucleus incompressibility is evaluated using the coherent density fluctuation model with the extended relativistic mean field density. The relativistic energy dens…

Investigating the correlations of bulk properties of hyperon star with dark matter

Rashmita Jena, Padmalaya Dash, S. K. Biswal

The strong gravitational pull of the neutron star leads to the accretion of dark matter (DM) inside the core of the neutron star. The accretion of DM affects the bulk properties of…

Core or Halo? Two-Fluid Analysis of Dark Matter-Admixed Quarkyonic Stars in the Multi-Messenger Era

Jeet Amrit Pattnaik, D. Dey, M. Bhuyan +2

For the first time, we explore dark matter (DM) admixed quarkyonic stars (DAQSs) within a two-fluid formalism, where the normal/visible sector is modeled by a quarkyonic equation o…

-mode oscillation of neutron star in a new relativistic hybrid model

D. Dey, Jeet Amrit Pattnaik, R. N. Panda +1

We investigate how the pulsation frequencies of axial gravitational-wave modes (-modes) in a non-rotating neutron star depend on its composition, particularly when including qua…

Exploring the giant monopole resonance in superheavy nuclei: A theoretical perspective

S. Kumar, Jeet Amrit Pattnaik, S. K. Singh +3

Within the relativistic mean field framework, in an extended Thomas-Fermi approximation, we calculate the binding energy and charge distribution radius for the latest superheavy nu…
