Visualizations of spherical FMS wave simulation sigma100 at t = 2R_NS/c. Top three rows are two-dimensional (2D) visualizations of the toroidal ideal electric field E^ϕ (top left), the radial E × B velocity v^r (middle left), the angular velocity v^θ (bottom left), the Lorentz factor Γ (top right), the fluid temperature T (middle right), and the magnetization accounting for the fluid temperature σ_hot (bottom right). Contours of poloidal magnetic flux are plotted as white solid lines; the contours are linearly spaced. A white (black) vertical dashed line is placed at x = 1.15R_×. Bottom row shows 1D equatorial slices (z/R_× = 0) of the FMS electromagnetic wave components B^θ and E^ϕ (left), and the radial four-velocity (right).
