Equilibria and oscillations of magnetised neutron stars [PDF]
, 2010 We investigate equilibrium configurations and oscillation spectra of neutron stars,modelled as rotating magnetised fluid bodies in Newtonian gravity. We also explorethe idea that these model neutron stars could have dynamics analogous to rigid-bodyfree ...

Dual Immobilization and Magnetic Manipulation of Magnetic Nanoparticles [PDF]
, 2011 By suitably bio-functionalizing the surfaces, magnetic nanoparticles are able to bind specific biomolecules, and may serve as vectors for delivering bio-entities to target tissues.

Magnetic fields on young, solar-type stars [PDF]
, 2013 This thesis describes an investigation aimed at using spectropolarimetric observations of the magnetic fields of young solar-type stars to improve the understanding of the early development of solar and stellar dynamos and activity cycles.

The Starspots and Magnetic Fields of Young Late-F Stars [PDF]
Observations of the magnetic activity of young solar-type stars offer insights into the early history of our Sun, its dynamo activity and planetary impacts.

THE LARGE-SCALE MAGNETIC FIELDS OF ADVECTION-DOMINATED ACCRETION FLOWS [PDF]
, 2011 We calculate the advection/diffusion of the large-scale magnetic field threading an advection-dominated accretion flow (ADAF) and find that the magnetic field can be dragged inward by the accretion flow efficiently if the magnetic Prandtl number P-m ...

Magnetic fields in O-type stars measured with FORS 1 at the VLT [PDF]
, 2009 The presence of magnetic fields in O-type stars has been suspected for a long time. The discovery of such fields would explain a wide range of well documented enigmatic phenomena in massive stars, in particular cyclical wind variability, Hα emission ...

The Astrophysical JournalWe study the properties of sub-Alfvénic magnetohydrodynamic (MHD) turbulence, i.e., turbulence with Alfvén mach number M _A = V _L / V _A < 1, where V _L is the velocity at the injection scale and V _A is the Alfvén velocity.

Solar Force-free Magnetic Fields
Living Reviews in Solar Physics, 2012 The structure and dynamics of the solar corona is dominated by the magnetic field. In most areas in the corona magnetic forces are so dominant that all non-magnetic forces like plasma pressure gradient and gravity can be neglected in the lowest order ...

Fractality of Magnetic Helicity Distribution in the Solar Corona
The Astrophysical JournalWe find a universal power-law scaling of magnetic helicity distribution in the solar corona. Magnetic helicity is a dynamical invariant for ideal magnetohydrodynamics (MHD) and characterizes complex magnetic field structure by measuring the degree of ...

The Astrophysical JournalWe present the first results of one extremely high-resolution, nonradiative magnetohydrodynamical cosmological zoom-in simulation of a massive cluster with a virial mass of M _vir = 2.0 × 10 ^15 solar masses. We adopt a mass resolution of 4 × 10 ^5 M _⊙
