This thesis presents a study of quiet-Sun magnetic features in the solar photosphere.
Magnetic fields in the quiet Sun organize on small spatial scales, evolve very rapidly, and …

Understanding the dynamics and energetics of the solar atmosphere requires a good
understanding of photospheric magnetic fields, particularly on small spatial scales. Through …

We report on the dynamical interaction of quiet-Sun magnetic fields and granular convection
in the solar photosphere as seen by Sunrise. We use high spatial resolution (0 farcs 15–0 …

Modern observations of the solar surface performed with high polarimetric sensitivity and
high spatial resolution reveal how magnetic fields are present almost everywhere on the …

We study the relation between mesogranular flows, convectively driven sinks and magnetic
fields using high spatial resolution spectropolarimetric data acquired with the Imaging …

Context. Over the past 20 yr, the quietest areas of the solar surface have revealed a weak
but extremely dynamic magnetism occurring at small scales (< 500 km), which may provide …

Small bipolar magnetic features are observed to appear in the interior of individual granules
in the quiet Sun, signaling the emergence of tiny magnetic loops from the solar interior. We …

Most of our knowledge of solar surface magnetism comes from the analysis of polarization
spectra. The Stokes spectra contain detailed information on the structure and dynamics of …

We analyze two regions of the quiet Sun (35.6× 35.6 Mm 2) observed at high spatial
resolution (≲ 100 km) in polarized light by the IMaX spectropolarimeter on board the …
