Descripción
Most of the visible light coming from the Sun originates in the solar
photosphere. Numerical simulations are a common tool to study the solar
atmosphere starting from the basic laws of physics and few additional
assumptions. This thesis presents results of three-dimensional radiative
magnetohydrodynamic simulations of the quiet-sun, plage and sunspot
umbra. These simulations are used to compute synthetic observations that
can be compared to the real observations. Each chapter of this thesis
tackles a different problem: the solar abundance of indium, the
formation of the only photospheric spectral line that shows activity
variation, the formation of the spectral lines in the horizontal
supersonic flows caused by convective motions, the center-to-limb
variation of the emergent continuum and the spectropolarimetric
diagnostic of the simulated sunspot umbra.
