The next time you plan a quiet evening under a salted sky, with hopes of bathing your eyes in the ancient light of a majestic star cluster, be sure that your...
Small magnetic structures in the photosphere, radiative properties
The three dimensional structure of small magnetic field features in the photosphere, their dynamic behavior and their radiative properties are studied. We...
