Kilogauss magnetic fields from simulations of small-scale dynamo action in the convective envelope of a white dwarf
Fabio Riva, Tim Cunningham, Hans-Günter Ludwig +2
About 20% of white dwarfs are observed to host large-scale magnetic fields, but the origin of white dwarf magnetism remains uncertain. Small-scale turbulent dynamos (SSDs), which e…
On the influence of magnetic topology on the propagation of internal gravity waves in the solar atmosphere
G. Vigeesh, M. Roth, O. Steiner +1
The solar surface is a continuous source of internal gravity waves (IGWs). IGWs are believed to supply the bulk of the wave energy for the lower solar atmosphere, but their existen…
Interaction of magnetic fields with a vortex tube at solar subgranular scale
C. E. Fischer, G. Vigeesh, P. Lindner +3
Using high-resolution spectropolarimetric data recorded with the Swedish 1 m Solar Telescope, we have identified several instances of granular lanes traveling into granules. These…
On The Evolution of Magnetic White Dwarfs
P. -E. Tremblay, G. Fontaine, B. Freytag +5
We present the first radiation magnetohydrodynamics simulations of the atmosphere of white dwarf stars. We demonstrate that convective energy transfer is seriously impeded by magne…
Three-dimensional magnetohydrodynamic simulations of M-dwarf chromospheres
S. Wedemeyer, H. -G. Ludwig, O. Steiner
We present first results from three-dimensional radiation magnetohydrodynamic simulations of M-type dwarf stars with CO5BOLD. The local models include the top of the convection zon…
Numerical simulations of wave propagation in the solar chromosphere
C. Nutto, O. Steiner, M. Roth
We present two-dimensional simulations of wave propagation in a realistic, non-stationary model of the solar atmosphere. This model shows a granular velocity field and magnetic flu…
