Axion sourcing in dense stellar matter via CP-violating couplings
Filippo Anzuini, Antonio Gómez-Bañón, José A. Pons +2
Compact objects such as neutron stars and white dwarfs can source axion-like particles and QCD axions due to CP-violating axion-fermion couplings. The magnitude of the axion field…
Spin evolution of a proto-neutron star
G. Camelio, L. Gualtieri, J. A. Pons +1
We study the evolution of the rotation rate of a proto-neutron star, born in a core-collapse supernova, in the first seconds of its life. During this phase, the star evolution can…
Relativistic models of magnetars: the twisted-torus magnetic field configuration
R. Ciolfi, V. Ferrari, L. Gualtieri +1
We find general relativistic solutions of equilibrium magnetic field configurations in magnetars, extending previous results of Colaiuda et al. (2008). Our method is based on the s…
Unstable g-modes in Proto-Neutron Stars
V. Ferrari, L. Gualtieri, J. A. Pons
In this article we study the possibility that, due to non-linear couplings, unstable g-modes associated to convective motions excite stable oscillating g-modes. This problem is of…
Relativistic r-modes and shear viscosity
L. Gualtieri, J. A. Pons, J. A. Miralles +1
We derive the relativistic equations for stellar perturbations, including in a consistent way shear viscosity in the stress-energy tensor, and we numerically integrate our equation…
A self-consistent model of isolated neutron stars: the case of the X-ray pulsar RX J0720.4-3125
J. F. Perez-Azorin, J. A. Pons, J. A. Miralles +1
We present a unified explanation for the observed properties of the isolated neutron star RX J0720.4-3125 by obtaining, for the first time, a self-consistent model that accounts si…
