Edisher Kh. Kaghashvili (2012) Can the Observed Wave Spectrum Explain the Solar Puzzle? National Solar Observatory Colloquium, Sunspot, NM. Aug. 1, 2012.

The source of energy for both coronal heating and wind acceleration is long known, but the exact nature of the photospheric energy transport and deposition is still a puzzle. It was long known theoretically, but recent observations undoubtedly confirmed an important role that Alfven waves play in these processes. While the observed spectrum is in the low-frequency range, existing wave dissipation mechanisms favor the high-frequency spectrum that can effectively interact with particles. In this talk, I discuss a new process of the wave energy deposition that is effective for the observed low frequency spectrum.
