“Coronal heating revisited. Waves, turbulence, reconnection, spicules: how are they all connected?”
Session organizers:
Andrea Verdini, Royal Observatory Belgium (verdini@oma.be)
Robert W. Walsh, University of Central Lancashire, UK (rwwalsh@uclan.ac.uk)
We would like to invite you to submit your abstract to the above session (E2.5) at the 39th COSPAR Scientific Assembly to be held in Mysore, India (14-22 July, 2012).
Recent observations reveal the presence of jets and spicules that may be carrying hot plasma into the corona at considerable speeds. It has been argued that this phenomena could represent a major contribution to solving the coronal heating problems.Yet, estimates of their occurrence rate, filling factor, energy, and mass are still preliminary. Moreover, jets and spicules are often associated with the ingredients of classical coronal heating paradigms: magnetic reconnection, waves and turbulence.
Authors are invited to present observational and theoretical/numerical work aiming to classify the possible coronal heating processes in terms of their main features: duration, energy release, rate and place of occurrence. The spatial and temporal resolution of current and future space-borne instrumentation as well as an extensive solar monitoring provide opportunity to enrich datasets with the accompanying statistical analysis of these candidate heating theories. However, is there a dominant mechanism which can be discriminated in the quiet Sun, active regions, and coronal holes? Can these dynamical and/or impulsive features work together and which are their connections?
NOTE: Abstract deadline: 10 February 2012
