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 …

Metric-affine effects in crystallization processes of white dwarfs

S Kalita, L Sarmah, A Wojnar - Physical Review D, 2023 - APS
We analyze the effects of modified gravity on specific heats of electrons and ions, Debye
temperature, crystallization process, and cooling mechanism in white dwarfs. We derive the …

Stellar equilibrium configurations of white dwarfs in the f(RT) gravity

GA Carvalho, RV Lobato, P Moraes… - The European Physical …, 2017 - Springer
In this work we investigate the equilibrium configurations of white dwarfs in a modified

White dwarf critical tests for modified gravity

RK Jain, C Kouvaris, NG Nielsen - Physical Review Letters, 2016 - APS
Scalar-tensor theories of gravity can lead to modifications of the gravitational force inside
astrophysical objects. We exhibit that compact stars such as white dwarfs provide a unique …
