electromagnetic waves. It is crucial to validate the theories and models of the most …

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 …

Gravitational waves from neutron-star mountains

F Gittins - Classical and Quantum Gravity, 2024 - iopscience.iop.org
Rotating neutron stars that support long-lived, non-axisymmetric deformations known as
mountains have long been considered potential sources of gravitational radiation. However …

Anisotropic magnetized white dwarfs: unifying under-and overluminous peculiar and standard type ia supernovae

D Deb, B Mukhopadhyay, F Weber - The Astrophysical Journal, 2022 - iopscience.iop.org
Ever since the observation of peculiar overluminous Type Ia supernovae (SNeIa), exploring
possible violations of the canonical Chandrasekhar mass limit (CML) has become a …

Cooling Process of White Dwarf Stars in Palatini f(R) Gravity

S Kalita, L Sarmah, A Wojnar - Universe, 2022 - mdpi.com
A simple cooling model of white dwarf stars is re-analyzed in Palatini f (R) gravity. Modified
gravity affects the white dwarf structures and consequently their ages. We find that the …

Gravitational wave in f (R) gravity: possible signature of sub-and super-Chandrasekhar limiting-mass white dwarfs

S Kalita, B Mukhopadhyay - The Astrophysical Journal, 2021 - iopscience.iop.org
After the prediction of many sub-and super-Chandrasekhar (at least a dozen for the latter)
limiting-mass white dwarfs (WDs), hence apparently a peculiar class of WDs, from the …

Formation, possible detection and consequences of highly magnetized compact stars

B Mukhopadhyay, M Bhattacharya - Particles, 2022 - mdpi.com
Over the past several years, there has been enormous interest in massive neutron stars and
white dwarfs due to either their direct or indirect evidence. The recent detection of …
