Magneto-acoustic waves during transient events

Sandra Milena Conde Cuellar

IAG/USP

Waves represent a source of energy to balance the loss of heat in the solar atmosphere. Acoustic waves can heat regions from the photosphere to the lower corona. However, in the solar corona the temperature can reach 10 million Kelvins due to the Alfvén waves. On the other hand, waves in coronal loops and solar flares are linked. This relation can be explained through the magnetic configuration of the active region.
In this talk, I shall show the temperature and number density along of coronal loops, during the B and C class flares. In the same manner, I shall describe the relation between magnetic field, magneto-acoustic waves and brightness distribution, along the coronal loops.
