Spectrophotometric analysis of Ellerman bombs in the Ca <b>II</b>, H$\mathsf{\alpha}$, and UV range

Abstract

Context.Even if Ellerman bombs have been observed in the Hα line within emerging magnetic flux regions since the early 20th century, their origin and the mechanisms that lead to their formation have been strongly debated. Recently, new arguments in favor of chromospheric magnetic reconnection have been advanced. Ellerman bombs seem to be the signature of reconnections that take place during the emergence of the magnetic field.
