Stratifications for Run A of density of ionized hydrogen (top left), pressure (top right), temperature (bottom left), and velocity (bottom right) computed 172 yr after the great eruption of η Car. The bars on the right side of the panels are in units of cm⁻³, dyn cm⁻², K, and cm s⁻¹, respectively, and the computational domain axes are in units of cm. A further description of the figure is given in the text.
