Coronal heating, nanoflares, and MHD turbulence
AIP Conference Proceedings, 1996Coronal heating is at the origin of the X-ray emission and mass loss from the Sun and many other stars. While different scenarios have been proposed to explain the heating of magnetically confined and open regions of the corona, they all rely on the transfer, storage and dissipation of the abundant energy present in photospheric motions.

Micro/Nanoflare Coronal Heating
1991Almost all strong continuous deformations of an initially uniform magnetic field in an infinitely conducting fluid cause the field to develop internal tangential discontinuities as the field relaxes to equilibrium. It is suggested that the dissipation at the tangential discontinuities in the bipolar magnetic fields of active regions is the principal ...

Nanoflares and heating of the solar corona
Journal of Astrophysics and Astronomy, 2006Coronal heating by nanoflares is presented by using observational, analytical, numerical simulation and statistical results. Numerical simulations show the formation of numerous current sheets if the magnetic field is sheared and bipoles have unequal pole strengths. This fact supports the generation of nanoflares and heating by them.

Effects of Temperature Bias on Nanoflare Statistics
The Astrophysical Journal, 2002Statistics of solar flares, microflares, and nanoflares have been gathered over an energy range of some 8 orders of magnitude, over E ≈ 1024-1032 ergs. Frequency distributions of flare energies are always determined in a limited temperature range, e.g., at T ≈ 1-2 MK if the 171 and 195 A filters are used from an extreme ultraviolet telescope (the Solar

Formation Conditions and Energetics of Solar Nanoflares
Geomagnetism and Aeronomy, 2017The energy potential of solar nanoflares is estimated with a new approach proposed by the author. This approach is based on the drift mechanism for the formation of a dense loop structure in the magnetic field of a bipolar source. The densification process is assumed to proceed until the appearance of unmagnetized protons.

Hinode Investigations of Microflares and Nanoflares
2018Microflares and nanoflares are small energy release phenomena in the Sun. As their occurrence rate is high, these events may contribute to the heating of the solar atmosphere. The three instruments onboard the Hinode satellite enable us to investigate the physical processes and measure the energy releases of microflares and nanoflares.
