Spectral Signatures of Synthetic Solar Plage : Bridging the gap between theory and observations

Moa Skan

In this thesis, I investigate the properties and dynamics of structures in the solar atmosphere, together with important physical processes required in order to detect, numerically model and analyse them. The understanding of how these structures are formed, driven and how their …

Why every observatory needs a disco ball

Robert Cumming, A. G. M. Pietrow, Livia Pietrow, Maria Cavallius et autres

Abstract Commercial disco balls provide a safe, effective and instructive way of observing the Sun. We explore the optics of solar projections with disco balls, and find that while sunspot observations are challenging, the solar disk and its changes during eclipses are …

Small-scale loops heated to transition region temperatures and their chromospheric signatures in the simulated solar atmosphere

Moa Skan, S. Danilović, J. Leenaarts, Flavio Calvo et autres

Context.Recent observations have revealed loop-like structures at very small scales visible in observables that sample the transition region (TR) and even coronal temperatures. These structures are referred to as either ‘unresolved fine structures’, ‘dynamic cool loops’, ‘miniature hot loops’ or ‘campfires’ depending …

Small-scale loops heated to transition region temperatures and their chromospheric signatures in the simulated solar atmosphere

Moa Skan, S. Danilovic, J. Leenaarts, F. Calvo et autres

Recent observations revealed loop-like structures at very small scales visible in observables that sample transition region (TR) and coronal temperatures. Their formation remains unclear. We study an example of a bipolar system in realistic magnetohydrodynamic simulations and forward synthesis of spectral lines …
