The effect of a spiral-like perturbation in the orbits of an axisymmetric galactic potential is studied using surfaces of section. It is found that the...
In this contribution, the main characteristics of near infrared spectropolarimetric measurements are described, putting especial emphasis on the techniques to...
Stokes profiles emerging from the magnetized quiet photosphere and observed by the Solar Optical Telescope (SOT) spectropolarimeter (SP) aboard the Hinode...
Storage of toroidal magnetic field below the solar convection zone
Simulations of erupting flux tubes in the thin flux tube approximation show that essential properties of sunspots can only be explained if the initial field...
In this contribution, several aspects of the discovery of the Milky Way hosting a central bar are briefly reviewed, as well as some minimal introduction about...
