Investigating Twin Star Equation of States in Light of Recent Astrophysical Observations
Shamim Haque, Atharva Shinde, Asim Kumar Saha +2
Twin stars are predicted to exist in nature if the hadron-to-quark phase transition is strong enough to form a new branch of hybrid stars, separated from the branch of neutron star…
Curvature Effect on the Speed of Sound
Anshuman Verma, Asim Kumar Saha, Ritam Mallick
The speed of sound refers to the rate at which information travels from one point to another. It is a positive quantity and bounded by causality. It is defined as the rate of chang…
Imprints of Non-Symmetric Dark Matter Halos on Magnetars: A Two-Fluid Perspective
Asit karan, Anil Kumar, Monika Sinha +1
In this study, we investigate the impact of dark matter on the structure and deformation of magnetars. We assume a perturbative approach for the magnetic field deformation and that…
Probing the Internal Structure of Neutron Stars: A Comparative Analysis of Three Different Classes of Equations of State
Anshuman Verma, Asim Kumar Saha, Tuhin Malik +1
Sound speed can be an important tool in unraveling the nature of matter that exists at the cores of neutron stars. In this study, we investigate three major classes of equations of…
Comparison of Equations of State for Neutron Stars with First-Order Phase Transitions: A Qualitative Study
Anshuman Verma, Asim Kumar Saha, Ritam Mallick
The equation of state is fundamental in describing matter under the extreme conditions characteristic of neutron stars and is central to advancing our understanding of dense matter…
Causality for first-order phase transition and its implication on the maximum mass of neutron stars
Asim kumar Saha, Ritam Mallick
Causality is an essential factor in determining the maximum mass of a neutron star. Previous works study causality for smooth equations of state. The density at the core of neutron…
