MAGNETIC TWIST OF EUV CORONAL LOOPS WELL-TRACED IN TRACE IMAGES: EVIDENCE FOR MAGNETIC RECONNECTION ORIGIN OF CORONAL LOOPS?

摘要

The measurements of magnetic twist of EUV coronal loops for 14 loops are presented here. EUV coronal loops are thin, EUV-emitting structures of hot plasma tracing magnetic field lines in the corona. The constriction of plasma into a loop without dispersio
