Systematic study of scalar, vector, and mixed density dependencies in relativistic mean-field descriptions of hyperonic matter in neutron stars
Aprajita Shrivastava, Prasanta Char, Sakshi Gautam +1
We investigate the equation of state (EOS) of hyperonic neutron star (NS) matter within a density-dependent relativistic mean-field (DDRMF) framework. The effects of scalar, vector…
Implication of multimessenger observations on the relativistic mean-field equation of state of dense nuclear matter and skin thickness of nuclei
Rahul Kumar, Prasanta Char, Rana Nandi
The composition and properties of infinite nuclear matter under extreme conditions of temperature and pressure remain incompletely understood. In this work, we constrain the equati…
Properties of neutron stars with hyperons within a generalized relativistic approach
Prasanta Char, Chiranjib Mondal, Timothé Alezraa +2
In this work, we study the effects of -hyperons on neutron star properties employing a generalized relativistic framework for the equation of state (EOS). Different choices for…
Systematics from NICER Pulse Profiles Drive Uncertainty in Multi-Messenger Inference of the Neutron Star Equation of State
Bhaskar Biswas, Prasanta Char
We present new constraints on the neutron star equation of state (EOS) and mass distribution using a unified Bayesian inference framework that incorporates latest NICER measurement…
Stellar properties indicating the presence of hyperons in neutron stars
Andreas Bauswein, Aristeidis Nikolaidis, Georgios Lioutas +7
We describe distinctive stellar features indicating the presence of hyperons in neutron stars as compared to purely nucleonic systems. A strongly negative curvature of the mass-rad…
Exploring the limits of nucleonic metamodelling using different relativistic density functionals
Prasanta Char, Chiranjib Mondal
In this work, we explore two classes of density dependent relativistic mean-field models, their predictions of proton fractions at high densities and neutron star structure. We hav…
