Impacts of dark matter interaction on nuclear and neutron star matter within the relativistic mean-field model
H. C. Das
This thesis explores the effects of dark matter (DM) on neutron stars (NSs) using the relativistic mean-field (RMF) model. The effects of DM on NS properties, including the mass-ra…
The Impact of Anisotropy on Neutron Star Properties: Insights from I-f-C Universal Relations
Sailesh Ranjan Mohanty, Sayantan Ghosh, Pinku Routaray +2
This study presents a universal relation for anisotropic neutron stars, called the relation, which accounts for the local anisotropic pressure using the Quasi-Local (QL) Mo…
Radial Oscillations of Dark Matter admixed Neutron Stars
Pinku Routray, H. C. Das, Souhardya Sen +3
Within the relativistic mean-field model, we investigate the properties of dark matter (DM) admixed neutron stars, considering non-rotating objects made of isotropic matter. We ado…
Pasta properties of the neutron star within effective relativistic mean-field model
Vishal Parmar, H. C. Das, Ankit Kumar +3
We study the properties of pasta structures and their influence on the neutron star observables employing the effective relativistic mean-field (E-RMF) model. The compressible liqu…
Systematic study for the surface properties of neutron star
Ankit Kumar, H. C. Das, Jeet Amrit Pattnaik +1
[Background] In our earlier work {\bf [Phys. Rev. C 104, 055804 (2021)]}, we studied the surface properties of a neutron star, assuming it as a huge finite nucleus containing proto…
Crustal properties of a neutron star within an effective relativistic mean-field model
Vishal Parmar, H. C. Das, Ankit Kumar +2
We use the effective relativistic mean-field (E-RMF) model to study the crustal properties of the neutron star. The unified equations of state (EoS) are constructed using recently…
Constraining nuclear matter parameters and neutron star observables using PREX-2 and NICER data
S. K. Biswal, H. C. Das, Ankit Kumar +1
We try to constraints some of the nuclear matter parameters such as symmetry energy () and its slope () from the recent inferred data of the PREX-2. Other nuclear matter para…
Impacts of dark matter on the -mode oscillation of hyperon star
H. C. Das, Ankit Kumar, S. K. Biswal +1
We investigate the -mode oscillation of the dark matter admixed hyperon star within the relativistic Cowling approximation. The macroscopic properties are calculated with the re…
Incompressibility and Symmetry Energy of Neutron Star
Ankit Kumar, H. C. Das, S. K. Patra
We trace a systematic and consistent method to precisely numerate the magnitude range for various structural and isospin compositional properties of the neutron star. Incompressibi…
Rotating neutron stars with quark cores
I. A. Rather, Usuf Rahaman, M. Imran +3
The rotating neutron star properties are studied with a phase transition to quark matter. The density-dependent relativistic mean-field model (DD-RMF) is employed to study the hadr…
BigApple force and its implications to finite nuclei and astrophysical objects
H. C. Das, Ankit Kumar, Bharat Kumar +2
The secondary component of the GW190814 event left us with a question, "whether it is a supermassive neutron star or lightest black-hole?". Recently, Fattoyev et al. have obtained…
Impacts of dark matter on the curvature of the neutron star
H. C. Das, Ankit Kumar, Bharat Kumar +2
The effects of dark matter (DM) on the curvatures of the neutron star (NS) are examined by using the stiff and soft relativistic mean-field equation of states. The curvatures of th…

Ankit Kumar, H. C. Das, S. K. Biswal +2
We study the thermal effects on the nuclear matter (NM) properties such as binding energy, incompressibility, free symmetry energy and its coefficients using NL3, G3 and IU-FSU par…
Application of the coherent density fluctuation model to study the nuclear matter properties of finite nuclei within the relativistic mean-field formalism

We obtained a density-dependent analytical expression of binding energy per nucleon for different neutron-proton asymmetry of the nuclear matter (NM) with a polynomial fitting, whi…
Constraining Bag constant for Hybrid Neutron stars
I. A. Rather, A. Kumar, H. C. Das +3
We study the star matter properties for Hybrid equation of state (EoS) by varying the bag constant. We use the Effective-Field-Theory motivated Relativistic Mean-Field model (E-RMF…

H. C. Das, Ankit Kumar, Bharat Kumar +4
We study the dark matter effects on the nuclear matter parameters characterising the equation of states of super dense neutron-rich nucleonic-matter. The observables of the nuclear…
