Modelling and statistical analysis of small-scale bursts in the lower solar atmosphere

ABSTRAKT / ABSTRACT :

Small-scale energetic phenomena (compact bursts – CBs) are frequently observed in the
lower solar atmosphere in the optical and UV spectral ranges as Ellerman bombs, IRIS
bursts, hot explosions, etc. They appear as intense, short time-scale brightenings,
mainly in solar active regions, such as emerging flux areas, plages, or around sunspots.
Modelling of these structures using NLTE codes and statistical analysis enables us to
diagnose these phenomena and determine their physical parameters. CBs can play an
important role in the heating of the chromosphere or lower corona. Current knowledge
about these events and the results of our recent work will be presented.
