We examine the process of element segregation by gravity in giant elliptical galaxies and X-ray clusters. We solve the full set of flow equations developed by Burgers for a multi-component fluid, under the assumption that magnetic fields slow the diffusion by a constant factor FB . Compared to the previous calculations that neglected the residual heat flow terms, we find that diffusion is faster by ∼ 20%. In clusters we find that the diffusion changes the local abundance typically by factors of… CONTINUE READING
