    • Asymptotic, non-linear solutions for ambipolar diffusion in one dimension 
      Hoyos, Jaime H.; Reisenegger, Andreas; Valdivia Hepp, Juan (WILEY-BLACKWELL, 2010-06-22)
      We study the effect of the non-linear process of ambipolar diffusion (joint transport of magnetic flux and charged particles relative to neutral particles) on the long-term behaviour of a non-uniform magnetic field in a ...
    • Dynamics of magnetic fields in neutron stars 
      Castillo Andahur, Francisco Javier (Universisdad de Chile, 2017)
      Como otro paso hacia la comprensión de la evolución a lo largo plazo del campo magnético en las estrellas de neutrones, ofrecemos las primeras simulaciones de difusión ambipolar en una estrella esférica. Restringiendonos ...
    • Evolution of random initial magnetic fields in stably stratified and barotropic stars 
      Becerra, Laura; Reisenegger, Andreas; Valdivia Hepp, Juan Alejandro; Gusakov, Mikhail E. (Oxford, 2022)
      Long-lived magnetic fields are known to exist in upper main-sequence stars, white dwarfs, and neutron stars. In order to explore possible equilibrium configurations of the magnetic field inside these stars, we have performed ...
    • The limits of bound structures in the accelerating Universe 
      Dünner, Rolando; Araya, Pablo A.; Meza Cofré, Andrés; Reisenegger, Andreas (BLACKWELL, 2006-03-01)
      According to the latest evidence, the Universe is entering an era of exponential expansion, where gravitationally bound structures will get disconnected from each other, forming isolated 'island universes'. In this scenario, ...
    • Magnetic field evolution in neutron stars: one-dimensional multi-fluid model 
      Hoyos, J.; Reisenegger, Andreas; Valdivia Hepp, Juan (EDP SCIENCES S A, 2008-09)
      Aims. This paper is the first in a series that aims to understand the long-term evolution of neutron star magnetic fields. Methods. We model the stellar matter as an electrically neutral and lightly-ionized plasma composed ...
    • On magnetic equilibria in barotropic stars 
      Armaza, Cristóbal; Reisenegger, Andreas; Valdivia Hepp, Juan (IOP PUBLISHING, 2015)
      Upper main-sequence stars, white dwarfs, and neutron stars are known to possess stable, large-scale magnetic fields. Numerical works have confirmed that stable magnetohydrodynamic equilibria can exist in non-barotropic, ...
