Eclipse observations of high-frequency oscillations in active region coronal loops
Eclipse observations of high-frequency oscillations in active region coronal loops
One of the mechanisms proposed for heating the corona above solar active regions is the damping of magnetohydrodynamic (MHD) waves. Continuing on previous work, we provide observational evidence for the existence of high-frequency MHD waves in coronal loops observed during the August 1999 total solar eclipse. A wavelet analysis is …
