INTERACTION BETWEEN FLARE-INDUCED SHOCKS

The interaction between two consecutive flare-induced shocks is discussed using a one-dimensional MHD model and the shock fitting method' The rarefaction waves appearing in the downstream region of the leading shock change the property of the tailing shock remarkably, and generates a strong reverse fast shock downstream it. The merging of the two flare-induced shocks leads to the formation of a contact surface, of which the density ratio is about 1.5.
