1. Quiescent Loop Heating Profiles with AIA Henry (Trae) Winter, Kerry Neal, Jenna Rettenmayer, & Piet Martens Montana State University--Bozeman

2. The Problem Priest,et al. (2000): The heating is distributed evenly along the coronal loop. Markus Aschwanden (2001): The heating occurs at the footpoints of coronal loops. F. Reale (2002): heating is at the apex of the loops

3. The Problem

4. 1998 1998 2003 EIT Filter Ratio 6.0 6.0 6.0 Line Ratio 6.5 6.6 6.6 EM Loci Multi-Thermal 6.2-6.3 6.3 Note: Temperature in Log[K] Will AIA make this any better?

5. Current Work Analyze a loop to see if different heating profiles provide an observale signal Using the parameters of a loop observed in SUMER by Cargill & Klimchuck (2004) –Power~10 24 ergs s -1 –Constant diameter: 7e8 cm –Half length: 7.5e9 cm Model the loop using a 1-D hydrodynamics with code varying heat profiles Watch the results
