This paper reviews the current status of the theoretical models
of the evolution of the magnetic fields of neutron stars other than magnetars.
It appears that the magnetic fields of neutron stars de...
Large Scale Magnetic Fields：Density Power Spectrum in Redshift Space
Cosmology magnetic fields MHD

2009/5/19
We compute the density redshift-space power spectrum in
the presence of tangled magnetic fields and compare it with existing observations.
Our analysis shows that if these magnetic fields originated...
What Helicity Can Tell Us about Solar Magnetic Fields
Sun magnetic fields helicity

2009/5/5
Concept of magnetic/current helicity was introduced to solar
physics about 15 years ago. Earlier studies led to discovery of such fundamental
properties as hemispheric helicity rule, and role of he...

2009/5/5
Since the structuring and variability of the Sun and other
stars are governed by magnetic fields, much of present-day stellar physics
centers around the measurement and understanding of the magnetic...

2009/3/31
In this article we study the equilibrium of polytropes in poloidal
magnetic field. The magnetic field is the solution of a nonhomogeneous Euler equation
for which we are able to give the general sol...
