One of the leading mechanisms for explaining the high temperature of the Sun’s corona is based on Parker’s conjecture that a sufficiently complex field will develop near-singular current sheets, leading to the onset of rapid magnetic reconnection and energy conversion. This topological dissipation mechanism remains a matter of debate, and is a key ingredient in the nanoflare model for coronal heating. I will discuss theory, simulations and observational support relating to this heating mechanism. [mehr]
