Abstract The quiet Sun observed in polarized light exhibits a rich and complex magnetic structuring which is still not fully resolved nor understood. The present work is intended to contribute to the debate about the origin of the quiet sun magnetic fields, in relation or not to the global solar dynamo. We present analysis of center-to-limb...

We report in this communication the rst experimental results in the visible range obtained by the Probability Imaging technique applied to close binary stars. Speckle data of the well known binary Del as well as the newly discovered one Moai1 (Carbillet et al. 1996) are processed. An analysis of the probability density functions, combined with...
