3D numerical MHD modeling of sunspots with radiation transport
MHD – radiative transfer – Sun sunspots – Sun photosphere – Sun magnetic
2010/11/10
Sunspot fine structure has been modeled in the past by a combination of idealized magneto-convection simulations and simplified models that prescribe the magnetic field and flow structure to a large d...
An uncombed inversion of multi-wavelength observations reproducing the Net Circular Polarization in a sunspots' penumbra
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
I derived a geometrical model of the penumbral magnetic field topology from an uncombed inversion setup that aimed at reproducing the NCP of simultaneous spectra in near-IR (1.56 mu) and VIS (630 nm) ...
Supersonic Downflows at the Umbra-Penumbra Boundary of Sunspots
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
High resolution spectropolarimetric observations of 3 sunspots taken with {\em Hinode} demonstrate the existence of supersonic downflows at or close to the umbra-penumbra boundary which have not been ...
Determining Absorption, Emissivity Reduction, and Local Suppression Coefficients inside Sunspots
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
The power of solar acoustic waves is reduced inside sunspots mainly due to absorption, emissivity reduction, and local suppression. The coefficients of these power-reduction mechanisms can be determin...
