| Abstract: |
Understanding the heating time scale is important for constraining models of active region emission.
Hinode observations of moss at the bases of high temperature active region core
loops are allowing us to study this problem in unprecedented detail. Here we discuss some of our recent
results studying the variability of moss properties such as intensity, magnetic flux, Doppler and non-thermal velocity.
We find that most of these quantities are relatively constant. One interpretation is that the heating is therefore
effectively steady, i.e., heating
events occur with a rapid repetition rate. Alternatively, the heating could be low frequency, but
only if it occurs on sub-resolution spatial scales. |
