Transverse waves observed in a fibril with the MiHI prototype
E. Petrova, T. Van Doorsselaere, M. van Noort +2
Context. Fine-scale structures of the solar chromosphere, particularly fibrils, are known to host various types of magnetohydrodynamic (MHD) waves that can transport energy to the…

Observations of Fan-Spine Topology by Solar Orbiter/EUI: Rotational Motions and Indications of Alfvén Waves
E. Petrova, T. Van Doorsselaere, D. Berghmans +3
Torsional Alfvén waves do not produce any intensity variation and are, therefore, challenging to observe with imaging instruments. Previously, Alfvén wave observations were repor…
