Plasma Flow In And Around Magnetic Flux Concentrations
Abstract
Introduction: The interaction of magnetic fields and plsma flows is one of the fundamental physical processes that leads to many of the dynamic effects observed on the Sun. The present work aims at the correlation of physical quantities such as line of sight magnetic field strength and the bisector velocity at small spatial scales. Methods: We have observed a solar region NOAA 8350 on 1998 October 8 with Universal Birefringent Filter (UBF) in 5576 Å, 6563 Å, 5571 Å continuum and line of sight magnetogram in 6302 Åsimultaneously with G-band images. Bisector velocities were measured for 5576 Å line. Results: Our data analysis reveals that bright points and flux sheets associated to upward and downward motions while micropores and pores associated to upward motions. These flux concentrations shows accelerated motions in deeper layers. Discussion: Upward and downward motions within magnetic flux concentrations is probably due to there dynamic behaviour.
