Solar Wind Heating Source Discovered

Ion cyclotron waves are made of protons that circle in wavelike-rhythms around the sun’s magnetic field.  According to a theory developed by Phil Isenberg (University of New Hampshire) and expanded by Vitaly Galinsky and Valentin Shevchenko (UC San Diego), ion cyclotron waves emanate from the sun; coursing through the solar wind, they heat the gas to millions of degrees and accelerate its flow to millions of miles per hour. Kasper’s findings confirm that ion cyclotron waves are indeed active, at least in the vicinity of Earth where the Wind probe operates.

Great news! The mechanism for heating the solar wind to millions of degrees while the photosphere remains around 6000 degrees has been unclear for decades. And the discovery has caught the attention of researchers attempting to build fusion power plants on Earth. The Sun’s ability to heat heavy ions might provide some clues on how to deal with contamination that cools the plasma inside a fusion reactor.
