SUMMARY:Flux emergence and solar dynamic events - Vasilis Archontis\, Scho
 ol of Mathematics and Statistics\, St Andrews University
DTSTART:20090601T150000Z

UID:TALK17138@talks.cam.ac.uk
CONTACT:Dr Geoffroy Lesur
DESCRIPTION:One of the most important processes\, responsible for many dyn
 amical phenomena observed in the Sun\, is the emergence of magnetic flux f
 rom the solar interior in active regions and the modification of the coron
 al magnetic field in response to the emergence. In fact\, magnetic flux em
 ergence might be responsible for the appearance of small-scale\nevents (e.
 g.\, compact flares\, plasmoids\, active-region-associated X-ray brighteni
 ngs) and large-scale events (e.g.\, X-class flares and CMEs).\nHowever\, i
 t is clear that the question of how exactly the magnetic fields rise throu
 gh the convection zone of the Sun and emerge through the photosphere and c
 hromosphere into the corona has still not been solved. Studying the proces
 s of flux emergence is an important step towards the understanding of the 
 dynamic coupling between the solar interior and the\nouter solar atmospher
 e.\nIn this talk\, we review the recent progress and discuss what further 
 developments are required\, to understand better this magnetic coupling in
  the Sun.
