Abstract

Microflares 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. Based on the Hinode observations, some of the events can be explained by magnetic reconnection, particle acceleration, and chromospheric evaporation, similar to those for large flares. By precise differential emission measure estimations with multiwavelength observations, it is now possible to investigate the signatures of smaller flares with no individual flare detection.
