ScienceDaily is reporting that a team of scientists have discovered that Helium may act as a "throttle" for the solar wind. The team hopes that this insight will provide them a better look inside the dynamics of space weather. "Because helium nearly vanishes from the solar wind at its minimum speed, the researchers believe helium might somehow set the minimum speed. Helium is not accelerated efficiently by any process thought to be propelling the solar wind. Instead, it has to be dragged along by the hydrogen: Solar wind hydrogen atoms exert a small electric field that drags the helium out along with it, according to the team."
