covariant density functional approach to the equation of state and composition of dense …

Equation of state of a dense and magnetized fermion system

EJ Ferrer, V de La Incera, JP Keith, I Portillo… - Physical Review C …, 2010 - APS
The equation of state of a system of fermions in a uniform magnetic field is obtained in terms
of the thermodynamic quantities of the theory by using functional methods. It is shown that …

Structure of ultra-magnetised neutron stars

D Chatterjee, J Novak, M Oertel - The European Physical Journal A, 2021 - Springer
In this review we discuss self-consistent methods to calculate the global structure of strongly
magnetised neutron stars within the general-relativistic framework. We outline why solutions …

Effects of anisotropy on strongly magnetized neutron and strange quark stars in general relativity

D Deb, B Mukhopadhyay, F Weber - The Astrophysical Journal, 2021 - iopscience.iop.org
We investigate the properties of anisotropic, spherically symmetric compact stars, especially
neutron stars (NSs) and strange quark stars (SQSs), made of strongly magnetized matter …

Consistent neutron star models with magnetic-field-dependent equations of state
