| Abstract: Switchbacks are sudden deflections of the magnetic field that are uniquitous in the inner Heliosphere. However, there is no consensus on their origin, with proposed sources ranging from local in-situ processes to deeper coronal dynamics.
The key question we investigate, is whether the properties of switchbacks carry the signature of the ~11 year solar Schwabe cycle, which would indeed provide constraints on their possible causes. To do so, we consider a large statistical ensemble of switchbacks observed by Parker Solar Probe (PSP) and evaluate the cycle-dependence of their physical properties, including deflection amplitude, duration, waiting time, and related parameters to the observing conditions. |
