| Abstract: |
Using numerical simulations of the magnetized solar photosphere and
radiative diagnostics of the simulated photospheric models, we further
analyse the physical nature of magnetic photospheric intergranular
vortices. We confirm the magnetic nature of the vortices and find
that most MHD Umov-Poynting flux is produced by horizontal vortex
motions in the magnetised intergranular lanes. In addition, we
consider possible ways to directly observe photospheric magnetic
vortices using spectropolarimetry. Although horizontal plasma
motions cannot be detected in the spectropolarimetric observations of
solar disk center, we find an observational signature of photospheric
vortices in simulated observations of Stokes-V amplitude asymmetry
close to the solar limb. Potential ways to find the vortices in the
observations are discussed. |
