THE 3-DIMENSIONAL STRUCTURES OF X-RAY BRIGHT POINTS

Recently, the Converging Flux Model has been proposed for X-ray bright points and cancelling magnetic features. The aim of this peice of wor k is to try and model theoretically specific X-ray bright points in th e framework of the Converging Flux Model. The observational data used includes a magnetogram showing the normal component of the magnetic fi eld at the photosphere and a high-resolution soft X-ray image from NIX T showing the brightenings in the lower solar.corona. By approximating the flux concentrations in the magnetograms with poles of the appropr iate sign and sense, the overlying three-dimensional potential field s tructure is calculated. Deduction of plausible motions of the flux sou rces are made which produce brightenings of the observed shape due to reconnection between neighbouring flux regions. Also the three-dimensi onal separatrix and separator structure and the way the magnetic field lines reconnect in three dimensions is deduced.
