Descripción
Context. IMaX/Sunrise has recently reported the temporal evolution of
highly dynamic and strongly Doppler shifted Stokes V signals in the
quiet Sun. Aims: We attempt to identify the same quiet-Sun jets
in the Hinode spectropolarimeter (SP) data set. Methods: We
generate combinations of linear polarization magnetograms with blue- and
redshifted far-wing circular polarization magnetograms to allow an easy
identification of the quiet-Sun jets. Results: The jets are
identified in the Hinode data where both red- and blueshifted cases are
often found in pairs. They appear next to regions of transverse fields
that exhibit quiet-Sun neutral lines. They also have a clear tendency to
occur in the outer boundary of the granules. These regions always
display highly displaced and anomalous Stokes V profiles.
Conclusions: The quiet Sun is pervaded with jets formed when new field
regions emerge at granular scales loaded with horizontal field lines
that interact with their surroundings. This interaction is suggestive of
some form of reconnection of the involved field lines that generates the
observed high speed flows.

Magnestismo Solar y Estelar
Los campos magnéticos son uno de los ingredientes fundamentales en la formación de estrellas y su evolución. En el nacimiento de una estrella, los campos magnéticos llegan a frenar su rotación durante el colapso de la nube molecular, y en el fin de la vida de una estrella, el magnetismo puede ser clave en la forma en la que se pierden las capas
