Transient induced MHD oscillations : A tool to probe the solar active regions View all abstracts by submitter

Dr. A.K. Srivastava   Submitted: 2011-10-07 01:37

Solar transients and eruptive phenomena which are ubiquitous in the solaratmosphere, can shed new light to the understanding of the outstanding problemslike coronal heating and the solar wind acceleration. Observations in theentire electromagnetic spectrum of such dynamical processes of large andsmall-scale transient/eruptive events, with highly dynamic magnetic fieldconfiguration, and energetic particles, provide crucial information about theplasma processes at mega-Kelvin temperature embedded in a complex magneticfield, and also energy build-up/energy-release processes, taking place in suchevents. One of the most important phenomenological aspects of solar eruptivephenomena is the induced magnetohydrodynamic (MHD) waves generated during theseenergetic processes, which carry a potential signature to probing the solaractive regions. In this paper, we briefly review the recent trends of thetransient (e.g., flares) induced quasi-periodic oscillations in the solaratmosphere and discuss their implications in diagnosing the solar activeregions, providing the clue to understanding local plasma dynamics and heating.
