SUMMARY:Can Alfvénic (magnetic) waves heat the solar atmosphere? - Dr. Ri

DESCRIPTION:The heating of the solar atmosphere to temperatures in excess 
 of a million degrees has proved a stubborn problem for astrophysicist. Whi
 le many heating scenarios have been suggested (e.g.\, nanoflares\, waves)\
 , evidence for a dominant mechanism is still evasive. It is believed by ma
 ny that the heating will occur on small spatial scales\, so high resolutio
 n observations are required to observe the necessary processes. Over the l
 ast decade\, the development of advanced observing instrumentation has all
 owed for the resolution of features on scales of 100 km. The resulting obs
 ervations have revealed that the solar atmosphere is replete with wave phe
 nomena\, in particular Alfvénic waves. These magnetic waves are relativel
 y difficult to dissipate and are able to transport energy efficiently thro
 ugh the solar atmosphere. \n   I will talk about the most recent observati
 ons of the Alfvénic waves in the solar atmosphere and what they reveal ab
 out the possibilities for wave heating. To begin with though\, I will prov
 ide a brief introduction to the Sun\, solar magnetism and magneto-hydrodyn
 amic wave theory.
