Polar Plume Simulation Polar plumes are being modelled by Steve Suess , Shyamsundar Parhi , and Martin Sulkanen.
Plumes are bright rays in coronal holes, visible between one and several solar radii.
They are denser and slower compared to interplume plasma and are modelled here as jets or wakes. A jet is introduced with a perscribed flow speed and an internal magnetic field. The surroundings are at rest and are also permeated by a magnetic field but with a different field strength. A7, pages 14,781 to 14,787. Click on image for animation.
