Scientists may have just cracked the sun's greatest mystery
In the new study, researchers investigated common fluctuations associated with the sun known as low amplitude decayless kink oscillations. These are fluctuations in coronal loops, or arch-like structures made of plasma that start in the photosphere and extend into the lower corona. These waves are relatively weak, but do not decay in strength over multiple cycles of fluctuation. As such, they may potentially supply a large amount of energy into the corona over time.
The scientists focused on the way in which these waves rippled either up and down, left and right, or at any angle in between, a property known as their polarization. The ability to analyze this aspect of the waves' 3-D geometry could shed light on their origins as well as how much energy they have available. However, scientists previously lacked a way to examine these waves from multiple lines of sight and therefore detect the phenomena's polarization.
