Descripción
We study the emergence of magnetic flux at very small spacial scales
(less than 1 arcsec) in the quiet Sun internetwork. To this aim, several
time series of spectropolarimetric maps were taken at disk center using
the instrument SP/SOT on board Hinode. The LTE inversion of the full
Stokes vector measured in the Fe I 6301 and 6302 lines will allow us to
retrieve the magnetic flux and topology in the region of study. We find
that the magnetic flux emerges typically within the granular structures.
In many cases, the horizontal magnetic field appears prior to any
significant amount of vertical field. As time goes on, the traces of the
horizontal field dissapear while the the vertical dipoles drift -carried
by the plasma motions- towards the surrounding intergranular lanes.
Sometimes they stay trapped there for a while but they eventually either
disappear by disgregation/cancelation or agregate to other magnetic
field concentrations giving rise to larger flux elements. The time scale
of these events is of the order of 10-20 minutes.
