[2.01] The Importance of Plasma Viscosity in Narrow Band Bright Point Observations

R.A. McMullen, D.W. Longcope, C.C. Kankelborg (Montana State University)

We explore the importance of compressional viscosity in models and observations of an X-ray bright point. Comparison of hydrodynamic models with and without compressive viscosity allow us to separate its physical effects during small scale heating events that differ only in the presence or absence of viscous effects. Heating models are designed to emulate TRACE and SOHO/MDI observations of a June 17, 1998 bright point transient brightening through variations in the temporal heat distribution. Analysis methods of data and model accuracy are explored.
