Abstract Type: Invited by SOC
Abstract: Decayless kink oscillations are ubiquitous in solar loops. Their persistent presence holds significant implications for our understanding of the solar coronal heating problem. However, since these oscillations do not exhibit the typical signs of decay often associated with kink oscillations driven by transient events, it is essential to identify the drivers or mechanisms that are powering these waves. Several candidates have been proposed, but conclusive evidence for any of them has yet to be identified. In this talk, I will present the evidence, or lack thereof, regarding the postulated wave drivers, based on high-resolution observations obtained from the Solar Orbiter spacecraft. Furthermore, I will discuss how these findings compare with the results obtained from a 3D magnetohydrodynamic (MHD) self-consistent simulation of a coronal loop. This comparison is crucial for identifying the characteristics of wave drivers and improving our understanding of the phenomena involved.
