Splinter Meeting Solar
From bright points to coronal mass ejections: the Sun on its various scales
Time: Wednesday September 23, 09:00-13:00 and 14:00-18:00 CEST (UTC+2)
Room: virtual room L
Convenor(s): C. Kuckein [1], I. Kontogiannis [1], A. Diercke [1], H. N. Smitha [2], A. J. Kaithakkal [3]
[1] AIP, [2] MPS, [3] KIS
The magnetic activity of the Sun manifests itself over a wide range of spatial and temporal scales. High energetic phenomena such as flares and coronal mass ejections are produced by
active regions on scales of tens of megameter, which host intense concentrations of magnetic fields including sunspots. In the quiet Sun, magnetic fields are structured on the smallest resolvable spatial scales (smaller than 100 km) and give rise to a plethora of interesting features
from small-scale emerging loops to bright points.
In the near future, new generation solar telescopes such as the Daniel K. Inouye Solar Telescope (DKIST) and the European Solar Telescope (EST), supplemented by the current GREGOR telescope, Vacuum Tower Telescope (VTT), and Swedish Solar Telescopes (SST) will enable us to probe the solar atmosphere and magnetic fields at an unprecedented detail. Storing and
processing large amounts of data produced by these telescopes will be quite challenging. Therefore, the development of novel data reduction techniques, inversion and modelling schemes will play a crucial role in the analysis and interpretation of those observations.
With the DKIST seeing its first light, now is the right time to bring together experts to discuss the latest advancements in large- and small-scale events on the Sun, from the photosphere up to the corona and the heliosphere. This splinter session provides such a forum, welcoming participants with a background in observational and theoretical/modelling in solar physics, as well as in solar instrumentation and data-analysis techniques. The overall goal is to strengthen the solar community and enable new connections between the participants, especially in the framework of large European projects such as the EST.
