Type Ia supernovae (SNe Ia) are important distance indicators, element factories, cosmic-ray
accelerators, kinetic-energy sources in galaxy evolution, and end points of stellar binary …

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
gravity theory, namely, f (R, T) gravity, for which R and T stand for the Ricci scalar and trace …

Nuclear processes in astrophysics: Recent progress

V Liccardo, M Malheiro, MS Hussein… - The European Physical …, 2018 - Springer
The question about the origin of the elements is a fascinating one, that scientists have been
trying to answer for the last seven decades. The formation of light elements in the primordial …

The extremes of thermonuclear supernovae

S Taubenberger - arXiv preprint arXiv:1703.00528, 2017 - arxiv.org
The majority of thermonuclear explosions in the Universe seem to proceed in a rather
standardised way, as explosions of carbon-oxygen (CO) white dwarfs in binary systems …

Effects of strong magnetic fields and rotation on white dwarf structure

B Franzon, S Schramm - Physical Review D, 2015 - APS
In this paper we compute models for relativistic white dwarfs in the presence of strong
magnetic fields. These models possibly contribute to superluminous SNIa. With an assumed …

White dwarfs in de Rham-Gabadadze-Tolley like massive gravity

B Eslam Panah, HL Liu - Physical Review D, 2019 - APS
The existence of possible massive white dwarfs more than the Chandrasekhar limit (1.45
M⊙, in which M⊙ is mass of the sun) is a challenging topic. In this regard, and motivated by …

Maximum mass of stable magnetized highly super-Chandrasekhar white dwarfs: stable solutions with varying magnetic fields

U Das, B Mukhopadhyay - Journal of Cosmology and …, 2014 - iopscience.iop.org
We address the issue of stability of recently proposed significantly super-Chandrasekhar

Modified Einstein's gravity as a possible missing link between sub-and super-Chandrasekhar type Ia supernovae

U Das, B Mukhopadhyay - Journal of Cosmology and …, 2015 - iopscience.iop.org
We explore the effect of modification to Einstein's gravity in white dwarfs for the first time in
the literature, to the best of our knowledge. This leads to significantly sub-and super …

Strongly magnetized white dwarfs and their instability due to nuclear processes
