Scientific paper

We study the spatial structure and temporal evolution of an X-ray bright point loop in order to understand the role of magnetic energy dissipation. We use a time-dependent gasdynamic model to simulate the corona and transition region in the x-ray bright point's coronal loop. For this work we model a bright point observed by TRACE, Yohkoh and SOHO on June 17, 1998, where the magnetic field geometry is derived from an extrapolation of magnetograms. We study the effects of various spatial and temporal distributions of heat deposition within the loop. The quantity of energy deposited and the location of the energy release is constrained by a model equilibrium magnetic field. We model the observed transient brightening of the bright point as a series of nanoflare events.
