Waves and oscillations have been observed in the Sun's atmosphere for over half a century.
While such phenomena have readily been observed across the entire electromagnetic …

The application of machine learning in solar physics has the potential to greatly enhance our
understanding of the complex processes that take place in the atmosphere of the Sun. By …

The magnetic field is the main driver of the activity in the solar upper atmosphere, but its
measurement is notoriously difficult. In order to determine the magnetic field in the …

The detection of Earth-like planets with the radial-velocity (RV) method is currently limited by
the presence of stellar activity signatures. On rotational time-scales, spots and plages (or …

Future ground-based telescopes, such as the 4-metre class facilities DKIST and EST, will
dramatically improve on current capabilities for simultaneous multi-line polarimetric …

Hinode is Japan's third solar mission following Hinotori (1981–1982) and Yohkoh (1991–
2001): it was launched on 2006 September 22 and is in operation currently. Hinode carries …

Context. Spectropolarimetric inversions are routinely used in the field of solar physics for the
extraction of physical information from observations. The application to two-dimensional …

Aims. Solar prominences contain a significant number of neutral species. The dynamics of
the ionised and neutral fluids composing the prominence plasma can be slightly different if …

Context. The solar chromosphere is heated to temperatures higher than predicted by
radiative equilibrium. This excess heating is greater in active regions where the magnetic …

Context. Our knowledge of the heating mechanisms that are at work in the chromosphere of
plage regions remains highly unconstrained from observational studies. While many heating …
