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…

Dirac vs. Majorana Dark Matter Imprints on Neutron Star Observables

M. Bhuyan, Jeet Amrit Pattnaik, S. K. Patra +1

The fundamental character of a fermionic dark matter, whether it is a Dirac or Majorana particle remains a key unresolved issue whose answer would profoundly affect dark-sector phe…

Quarkyonic Neutron Stars as Candidates for the GW230529 Mass-Gap Object

Jeet Amrit Pattnaik, S. K. Patra

We examine whether quarkyonic equations of state (EOS) can account for compact objects in the - mass range reported for the GW230529 gravitational-wave event. Th…

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…

Dark Matter Effects on the Curvature of Neutron Stars within the new Quarkyonic Model Coupled with Relativistic Mean Field Theory

Jeet Amrit Pattnaik, D. Dey, R. N. Panda +2

For the first time, we analyze the impact of dark matter (DM) on the curvature properties of quarkyonic neutron stars (NS) using a hybrid model based on quarkyonic-effective field…

-mode oscillations of dark matter admixed quarkyonic neutron star

D. Dey, Jeet Amrit Pattnaik, R. N. Panda +2

We systematically investigate mode oscillations ( = 2) in quarkyonic neutron stars with dark matter, employing the Cowling approximation within the framework of linearize…

Dark Matter Influence on Quarkyonic Stars: A Relativistic Mean Field Analysis

D. Dey, Jeet Amrit Pattnaik, H. C. Das +3

The formulation of quarkyonic matter consists of treating both quarks and nucleons as quasi-particles, where a cross-over transition occurs between the two phases. This work is bas…

Constraining the Surface Curvature of an Anisotropic Neutron Star

H. C. Das, Jeet Amrit Pattnaik, S. K. Patra

The anisotropy of pressure arises due to the various complex phenomena that happen inside the neutron star (NS). In this study, we calculate the degree of anisotropy inside the NS…
