Parker Solar Probe rules out magnetic bends for corona's heat
Summary: NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause for the sun's corona being 200 times hotter than its surface. Research from the University of Michigan, published in The Astrophysical Journal Letters, indicates that these bends, known as switchbacks, are absent in the corona, suggesting they do not contribute to its heating. Further data collection is planned for December 2024.
