Relativistic Oblique Shocks at Finite Temperature: Detachment Angle, Shock Polars, and the Turning Parameter
Rushikesh Ashok Sonkusale, Anshuman Verma, Ritam Mallick
Oblique shocks are ubiquitous in high-energy astrophysical environments, yet a systematic analytical treatment of how finite upstream temperature influences the maximum deflection…
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…
Effect of Magnetised Discontinuity on Diffusive Shock Acceleration
Anshuman Verma, Saksham Chandna, Divyansh Tripathi +1
We investigate the impact of magnetic fields and diffusion mechanisms on the energy spectra of particles accelerated via diffusive shock acceleration. We analyse magnetised shock j…
Modification of the universal relation between mass, radius and nonradial -mode oscillation in proto-neutron stars
Deepak Kumar, Asit Karan, Anshuman Verma +2
Neutron stars are usually assumed to be cold; however, in certain dynamical astrophysical scenarios such as newly born neutron stars or binary star mergers, the temperature effects…
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…
