Compressive Fluctuations Heat Ions in Space Plasma

New simulations carried out in part on the Space Plasma in Japan have found that the reason ions exist at higher temperatures than electrons in space plasma is because they are better able to absorb energy from compressive turbulent fluctuations in the plasma. These finding have important implications for understanding observations of various astronomical objects such as the images of the accretion disk and shadow of the M87 supermassive black hole captured by the Event Horizon Telescope.

In addition to the normal three states of matter (solid, liquid, and gas) which we see around us every day, there is an additional state called plasma which exists only at high temperatures...
