SUMMARY:Alfvén wave driven heating of the Solar chromosphere - Tony Arber
  (Warwick)
DTSTART:20170213T160000Z

UID:TALK69401@talks.cam.ac.uk
CONTACT:Robert Teed
DESCRIPTION:The solar chromosphere requires a local heat input of around 1
 0^7 erg/s/cm^2. It is also permeated by jets of cool dense meter which ris
 e into the corona - spicules. This talk will explain what the problem is a
 nd present a model which aims to answer both of these problems. The model 
 is based a Alfvén wave driving of an expanding flux tube which gives the 
 correct heating rate and rise speed for spicule-like structures. The talk 
 will end with a clear and detailed discussion of the limitations of the mo
 del and the prospects for these to be be overcome\, giving a definitive an
 swer\, in the next few years.
