Wind for the swift: how turbulence heats the solar corona ⚡ экспресс
Original: "Non-thermal particle acceleration in multi-species kinetic plasmas: universal power-law distribution functions and temperature inversion in the solar corona"
Chaotic electric fields in plasma, like a sieve, let only fast particles through, creating 'tails' of superspeeds and heating the solar corona to millions of degrees.

In plasma, like in the game 'King of the Hill', fast particles get an extra boost from turbulence, while slow ones stay in the shadows. This is what possibly heats the solar corona to millions of degrees—a mystery that puzzled physicists for 80 years.
🎯 The solar corona's temperature reaches 1–2 million kelvins, while the surface is about 5800 K. A kettle that heats the air around it more than its own handle.
🎬 Someday satellites might 'bathe' in the solar corona, filtering out fast particles to charge their batteries.
f(v) \propto v^{-5}
f(v) — the probability of finding a particle with speed v; v — particle speed
