Solar Orbiter Catches the Sun’s Missing High-Speed Vibrations
The Sun’s magnetic fields are a twisty, curvy, ever changing mess. In particular, our star’s polar regions host regions called polar coronal holes that host invisible magnetic highways that stretch out into interplanetary space. But there’s a lot we don’t know about how those highways actually work, and in particular how they give the particles that form the fast solar wind an extra “kick” that sends them zooming at hundreds of kilometers per second. A new paper from a team led by Dr. Yuhang Gao and Prof. Hui Tian at Peking University, and published recently in the journal National Science Review, thinks they might have found an answer by using high-speed shots from Solar Orbiter to detect never-before seen rapid, high-frequency magnetic waves in those areas.
