Descripción
A new three-dimensional model of the solar photosphere is presented in
this paper and made publicly available to the community. This model has
the peculiarity of having been obtained by inverting
spectro-polarimetric observations, rather than by using numerical
radiation hydrodynamical simulations. The data used here are from the
spectro-polarimeter onboard the Hinode satellite, which routinely
delivers Stokes I, Q, U, and V profiles in the 6302 Å spectral
region with excellent quality, stability, and spatial resolution
(approximately 0.3''). With this spatial resolution the major granular
components are resolved, which implies that the derived model needs no
micro- or macroturbulence to properly fit the widths of the observed
spectral lines. Not only does this model fit the observed data used for
its construction, but it can also fit previous solar atlas observations
satisfactorily.

Los campos magnéticos están presentes en todos los plasmas astrofísicos y controlan la mayor parte de la variabilidad que se observa en el Universo a escalas temporales intermedias. Se encuentran en estrellas, a lo largo de todo el diagrama de Hertzsprung-Russell, en galaxias, e incluso quizás en el medio intergaláctico. La polarización de la luz
