Kinetic Alfvén waves may be key to mystery of solar corona heating

Syed Ayaz, a researcher at The University of Alabama in Huntsville (UAH), has published a paper in Scientific Reports that builds on an earlier first-of-its-kind study that examined kinetic Alfvén waves (KAW) as a possible explanation for why the solar corona, the outermost layer of the sun's atmosphere, is approximately 200 times hotter than the surface of the sun itself.
