Torsional Waves Figure (Full Res)

Caption

Overview of observations and findings from the study.  Clockwise from left, the panels show the Sun’s corona observed by NASA’s Solar Dynamics Observatory using the Atmospheric Imaging Assembly in the extreme ultraviolet. This shows context for Cryo-NIRSP data—Inouye’s field of view is circled and the red dashed line shows spectrograph slit position. The upper right panel shows how the Cryo-NIRSP data evolve over time, and enhances extractions of the residual velocity signals on separate sides of thin coronal loops. The opposite signed velocities, colored blue and red in the figure, correspond to the twisting motions of the coronal feature, which is shown as well in the artist’s impression panel. Finally, these findings are corroborated using advanced 3D simulations of loops, which show the same type of signatures. (See paper for full details). Credit: Morton et al. (2025)
