Simulating Ellerman bomb-like events

by S. Danilovic A&A 601, A122


Discovered exactly a century ago, Ellerman bombs are prominent brightenings in seen in H-alpha observations of newly emerging active regions (sunspots) on the Sun. These events play a crucial role in our understanding of the magnetic reconnection on the Sun, and cartoon scenarios have been drawn for decades. This this paper shows in a 3D MHD simulation how these events form in a self-consistent, way and highlights that solar convection pushes together magnetic field of opposite magnetic polarity and through this initiates reconnection in the photosphere of the Sun. The H-alpha emission derived from the simulations shows the same characteristic flame-like appearance as that found in observations.
