Identification of periodic density structures in Solar Orbiter data: Radial evolution
C. Katsavrias, S. Di Matteo, L. Kepko +2
The quasi-Periodic density structures (PDSs) are quasiperiodic variations of solar wind density ranging from a few minutes to a few hours. They are trains of advected density struc…

Periodic Variations in Visible Light Brightness as Tracers of Fine Coronal Structures
Nathalia Alzate, Simone Di Matteo
The quiescent or dynamic nature of fine scale ray-like features in the sun corona, observed in visible light, is still an open question. Here, we show that most of daily and hourly…

Coronal Cells in Coronal Holes: Systematic Analysis and Implications for Coronal Evolution
Nathalia Alzate, Simone Di Matteo, Aleida Higginson
Using advanced processing techniques, we analyze high-cadence, high-resolution extreme ultraviolet images and show that, throughout the solar cycle, mid-latitude coronal holes (CHs…
