New theory explains how magnetic switchbacks form in the solar wind
Thursday, 30 November 2023 19:42
A new study develops a theory of how magnetic switchbacks are formed around the sun. This quantitative model can be used to predict magnetic field variations and potentially explain the heating and acceleration of the solar wind.
The lead author Dr. Gabor Toth worked with Dr. Bart van der Holst at the University of Michigan Department of Climate and Space Sciences and Engineering and Dr. Marco Velli at UCLA to publish the study, "Theory of Magnetic Switchbacks Fully Supported by Parker Solar Probe Observations," in The Astrophysical Journal.
Magnetic switchbacks are reversals of the radial magnetic field in the solar wind, which emanates from the surface of the sun. First seen sporadically in the seventies, magnetic switchbacks have recently been identified as a typical component of solar wind fluctuations in the inner heliosphere by the Parker Solar Probe.
Observations from the Parker Solar Probe revealed that these magnetic switchbacks consist of spherically polarized Alfvén waves, but until now, scientists had no concept of how these switchbacks were being formed.
