Can average speed of sound and thermodynamic response functions signal the exotic phases in neutron star cores?
Suman Pal, Gargi Chaudhuri
The speed of sound in dense nuclear matter is crucial for understanding neutron star structure and constraining the EOS. We have discussed in details the decomposition of speed of…
Can a hybrid star with constant sound speed parametrization explain the new NICER mass-radius measurements ?
Suman Pal, Gargi Chaudhuri
We present a reanalysis of NICER observations of PSR J0740+6620 and PSR J0030+0451 to test the consistency of various nuclear equations of state (EoS) within the framework of hybri…
Characterizing the quark-hadron mixed phase in compact star cores : sensitivity to nuclear saturation and quark-model parameters at finite-temperature
Suman Pal, Gargi Chaudhuri
A thorough knowledge of the quark-hadron phase transition in hot and dense matter is essential for constraining the equation of state of neutron stars. In this work, we study the t…
Calculation of the transport coefficients in neutron star
Utsab Gangopadhyaya, Suman Pal, Gargi Chaudhuri
In this work, we have calculated the transport coefficients: shear viscosity and thermal conductivity inside the neutron star core. Our calculation is based on the relativistic kin…
Radial Oscillations and Stability of Neutron Stars with Antikaon Condensates
Manisha Kumari, Sujan Kumar Roy, Soumen Podder +2
Radial oscillations provide a direct probe of the stability and compressibility of neutron stars and are highly sensitive to the equation of state of dense matter. In this work, we…
Density dependent speed of sound and its consequences in neutron stars
Suman Pal, Gargi Chaudhuri
We introduce a parametrized density-dependent speed of sound and construct an ensemble of equations of state for neutron stars which are found to closely resemble the realistic equ…

Suman Pal, Soumen Podder, Gargi Chaudhuri
In this work, we investigate the possibility of the compact object in HESS J1731-347 with and to be a hybrid star with…
Self-consistent thermodynamical treatment for quark matter in quasi-particle model at finite temperature
Suman Pal, Gargi Chaudhuri
In this work, we have studied the medium effects in strange quark matter in the framework of a grand-canonical ensemble using the phenomenological quasi-particle model. This model…

Medium Effects in MIT Bag Model for quark matter: Self consistent thermodynamical treatment
Suman Pal, Gargi Chaudhuri
The study of strange quark matter within the framework of the density-dependent MIT Bag model using the Grand Canonical ensemble is thermodynamically inconsistent. In this work, it…
Effect of dark matter interaction on hybrid star in the light of the recent astrophysical observations
Suman Pal, Gargi Chaudhuri
We have explored the effect of dark matter interaction on hybrid star (HS) in the light of recent astrophysical observational constraints. The presence of dark matter is assumed to…
Constraints on Density Dependent MIT Bag Model Parameters for Quark and Hybrid Stars
Soumen Podder, Suman Pal, Debashree Sen +1
We compute the equation of state (EoS) of strange quark stars (SQSs) with the MIT Bag model using density dependent bag pressure, characterized by a Gaussian distribution function.…
