Aims: The purpose of this paper is to characterize the statistical properties of solar granulation in the photosphere and low chromosphere up to 650 km. Methods...

The magnetic field plays a pivotal role in many fields of Astrophysics. This is especially true for the physics of the solar atmosphere. Measuring the magnetic...

Of the two solar lines, K I D1 and D2, almost all attention so far has been devoted to the D1 line, as D2 is severely affected by an O2 atmospheric band. This...

The temporal evolution of a solar prominence inserted in a three-dimensional magnetic flux rope is investigated numerically. Using the model of Titov & Démoulin...

We present an investigation of a single sunspot observed in the neutral Fe line at 1089.6 nm with the Tenerife Infrared Polarimeter at the Vacuum Tower...

We present a software simulator for the modeling of astronomical instrumentation, which includes platform effects and software processing. It is an end-to-end...

Context. Inversion codes are numerical tools used to infer physical properties from observations. Despite their success, the quality of current...

Context. One of the difficulties in extracting reliable information about the thermodynamical and magnetic properties of solar plasmas from spectropolarimetric...

The uncombed penumbral model proposed by Solanki & Montavon (cite{sol93a}) is used to understand some recent observational results found in penumbrae. This...
