Radiative activity of magnetic white dwarf undergoing Lorentz-force-driven torsional vibrations
magnetic white dwarf non-radial pulsations magneto-dipole emission
2010/11/11
We study radiative activity of magnetic white dwarf undergoing torsional vibrations about axis of its own dipole magnetic moment under the action of Lorentz restoring force. It is shown that pulsating...
Galactic Coronae in the Intracluster Environment: Semi-confined Stellar-feedback-driven Outflows
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
Recently X-ray observations have shown the common presence of compact galactic coronae around intermediate-mass spheroid galaxies embedded in the intracluster/intragroup medium (ICM). We conduct 2-D h...
Cosmic-ray current driven turbulence in shocks with efficient particle acceleration: the oblique, long-wavelength mode instability
High Energy Astrophysical Phenomena (astro-ph.HE) Plasma Physics (physics.plasm-ph)
2010/12/23
In order for diffusive shock acceleration (DSA) to accelerate particles to high energies, the energetic particles must be able to interact with magnetic turbulence over a broad wavelength range.
Resistivity-driven State Changes in Vertically Stratified Accretion Disks
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/22
We investigate the effect of shear viscosity and Ohmic resistivity on the magnetorotational instability (MRI) in vertically stratified accretion disks through a series of local simulations computed wi...
