Nonlinear steepening of a fast magneto-acoustic wave in the vicinity of a coronal magnetic null point

Abstract The interaction of a fast magneto-acoustic wave with a magnetic null point is studied in the context of the sympathetic flare phenomenon. Attention is paid to the steepening of the wave caused by the finite-amplitude effects in a non-uniform plasma environment. The null...

Decay length of slow magnetoacoustic waves in the solar corona using SDO/AIA and SolO/EUI-HRIEUV

Abstract Slow magnetoacoustic waves have been observed in the solar corona for decades; yet, existing theories do not fully explain the wide range of observed decay lengths, and measurements from different instruments frequently disagree. We present two events with simultaneous S...
