        1. The coronal heating problem. The so-called ‘coronal heating’ problem has existed for 75 years, since the solar corona was first demonstrated to contain plasma with temperatures of 1 million degrees kelvin and above, much higher than the photospheric surface temperature of approximately K [1,2].There have been many advances over this period, with great progress in Cited by: Chromospheric and Coronal Heating Mechanisms II.

      Abstract: Inspired by recent observations suggesting that photospheric magnetic flux cancellation occurs much more frequently than previously thought, we analytically estimated the energy released from reconnection driven by photospheric flux cancellation, and proposed that it can act as a mechanism for chromospheric and coronal heating (Priest et al., ).Author: P.

Except for F-stars, the chromospheric heating of rapidly rotating late-type stars is dominated by magnetic heating either through MHD wave dissipation (AC mechanisms) or through magnetic field dissipation (DC mechanisms).

coronal heating mechanisms can. We review the mechanisms which are thought to provide steady heating of chromospheres and coronae. It appears now fairly well established that nonmagnetic chromospheric regions of latetype stars are heated by shock dissipation of acoustic waves which are generated in the stellar surface convection zones.

Theoretical models of coronal heating mechanisms include the two main groups of DC (§ ) and AC models (§ ), which involve as a primary energy source chromospheric footpoint motion or upward leaking Alfvén waves, which are dissipated in the corona by magnetic reconnection, current cascades, MHD turbulence, Alfvén resonance, resonant absorption, or phase mixing.

The solar corona is highly structured by magnetic fields and the acoustic shocks which, according to early theories, should have acted as the coronal energy source have not been Cited by: 1.

There are a huge range of known energy release mechanisms on the Sun (see for example Erdélyi () and references therein), many of which have been implicated for coronal heating. At the. Thus coronal mass supply in transients is inextricably linked to direct chromospheric heating processes.

Using parametric models of a chromospheric heating function and of the pre-event chromosphere, an estimate is made of the extra power required to yield the emission measure enhancement of a large event evaporatively.Recent observations at high spatial resolution have shown that magnetic flux cancellation occurs on the solar surface much more frequently than previously thought, and so this led Priest et al to propose magnetic reconnection driven by photospheric flux cancellation as a mechanism for chromospheric and coronal heating.

In particular, they estimated analytically the amount of energy Cited by: 7.Mechanisms of Chromospheric and Coronal Heating: Proceedings of the International Conference, Heidelberg, 5 8 June by Peter Ulmschneider (Editor), E.R.
