trying to answer for the last seven decades. The formation of light elements in the primordial …

[HTML][HTML] Massive white dwarfs in gravity

RV Lobato, GA Carvalho, NG Kelkar… - The European Physical …, 2022 - Springer
In this work, we investigate the equilibrium configurations of massive white dwarfs (MWD) in

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 …

Crustal heating in accreting neutron stars from the nuclear energy-density functional theory-I. Proton shell effects and neutron-matter constraint

AF Fantina, JL Zdunik, N Chamel, JM Pearson… - Astronomy & …, 2018 - aanda.org
Context. X-ray observations of soft X-ray transients in quiescence suggest the existence of
heat sources in the crust of accreted neutron stars. Heat is thought to be released by …

Unmasking strange dwarfs with gravitational-wave observations

L Perot, N Chamel, P Vallet - Physical Review D, 2023 - APS
The advent of space-based gravitational-wave detectors like the Laser Interferometer Space
Antenna will allow us to observe signals, most of which are expected to be emitted by white …

Accreting neutron stars from the nuclear energy-density functional theory-II. Equation of state and global properties

AF Fantina, JL Zdunik, N Chamel, JM Pearson… - Astronomy & …, 2022 - aanda.org
Context. The accretion of matter onto the surface of a neutron star in a low-mass X-ray binary
triggers X-ray bursts, whose ashes are buried and further processed thus altering the …

Strongly magnetized white dwarfs and their instability due to nuclear processes

E Otoniel, B Franzon, GA Carvalho… - The Astrophysical …, 2019 - iopscience.iop.org
In this work, we study the properties of strongly magnetized white dwarfs (WDs), taking into
account the electron capture and pycnonuclear fusion reactions instabilities. The structure of …

Binary and ternary ionic compounds in the outer crust of a cold nonaccreting neutron star

N Chamel, AF Fantina - Physical Review C, 2016 - APS
The outer crust of a cold nonaccreting neutron star has been generally assumed to be
stratified into different layers, each of which consists of a pure body-centered cubic ionic …
